<p class="toc-link"> <a href="#toc">[table of contents]</a> </p>
<p>
Gallery is a web based software product that lets you manage
your photos on your own website. You must have your own website
with PHP and database support in order to install and use it. With Gallery
you can easily create and maintain albums of photos via an
intuitive interface. Photo management includes automatic
thumbnail creation, image resizing, rotation, ordering,
captioning, searching and more. Albums and photos can have
view, edit, delete and other permissions per individual
authenticated user for an additional level of privacy. It's
great for communities - give accounts to your friends and family
and let them upload and manage their own photos on your website!

The Gallery team retained <a
href="http://www.gulftech.org/">James Bercegay</a> of <a
href="http://www.gulftech.org/">Gulftech Research and
Development</a> to do a complete security audit of <b>Gallery 2.2
Release Candidate 1</b>.
</p>
<p>
<i>Recently we have performed a very thorough audit of the
Gallery2 code base. Our review consisted of both a complete
source code audit, as well as us performing multiple "real
world" attack scenarios against the Gallery2 application. During
the audit we identified multiple minor security issues which
have since been resolved by the Gallery2 developers. The result
is a much more secure Gallery2 application with enhanced
security features to keep your Gallery and its users as safe
and secure as possible.</i>

<p>
The Gallery team retained <a href="http://www.jibble.org/">Paul
Mutton</a> of <a
href="http://www.intershot.com/security/">Intershot Limited</a>
to do a complete security audit of <b>Gallery 2.1 Release Candidate
1</b>.
</p>
<p>
<i>The Gallery installer and Gallery application were
subjected to a manual web application security test. It is
important to note that such tests cannot be exhaustive and may
not discover all vulnerabilities. All tests were carried out
against a standalone installation of Gallery - no integrated
installations were tested (e.g. with phpBB or phpnuke). The
security of external tools used by the Gallery application,
such as graphics toolkits, were not included in this test. No
denial of service attacks were carried out against the
application server.</i>
</p>
<p>
<b>The development team resolved the security issues raised by
auditors during the release candidate phases.</b>
</p>
<div class="important">
<h3>Note</h3>
<p>
The Gallery project treats security issues very seriously. If
you find a security flaw, do not hesitate to email us at:

<h2><a name="whats_new">What&rsquo;s new in this release?</a></h2>
<p class="toc-link"> <a href="#toc">[table of contents]</a> </p>
<p>
Over four years of design and development have gone into making
Gallery 2 the best online photo management product available.
We have made it easy to add new features while keeping them in
separate modules so that you can customize it to only have the
ones that you want. For those of you who like standards, we
have strict XHTML compliance but give plenty of power to our
themes so that you can make it look the way that you want. It's
a powerful application and you're in the driver's seat.

Localizations now generally specify only a language rather than
language+country for better sharing of translations.
Country specific translations can still override the base translation.
</li>
<li>

<b> Gallery 1 migration </b>
<ul>
<li>
Custom fields from G1 can now be imported if the Gallery 2 custom
fields module is active.
</li>
<li>
Restricted permissions are now set for imported photos and
albums from G1 that are hidden. Gallery 2 does not yet
have a hidden feature so for now these items are
restricted by permissions.
</li>
<li>
Migration process now generates a report of any captions
that were trunctated to fit the field size of title or
summary in Gallery 2.
</li>
</ul>

<b> Localization </b> - Some translation fixes including several updates
to better support right-to-left languages. Gallery 2 now has 29 available
locales; over 90% translated in 6 languages, over 50% in 7 and partially
translated in 16 more! We still bundle all language data with the modules..
eventually we will have separate downloadable translations.
</li>
<li>
<b> Date formats </b> - Customizable date/time formats defined in Site Admin.
</li>
<li>
<b> Security </b> - Fixed minor cross site scripting flaw
where uploaded images could contain &lt;script&gt; tags in their

</h3>
<ol id="beta4-list" style="display:none">
<li>
<b> New Theme System </b> - You spoke -- we listened. The old
layout and theme system was far too complicated so we've
completely overhauled it leaving control firmly in the hands
of the theme designer while keeping it simple and easy to work with.
</li>
<li>
<b> Square Thumbnails </b> - This module now offers a mode to fit thumbnails
inside a square with a specified background color instead of cropping the image
into a square.
</li>
<li>
<b> CMYK Jpegs </b> - ImageMagick module can now detect jpegs using CMYK
colorspace and convert to RGB for display in the Gallery, still keeping the
original file available for download.
</li>
<li>
<b> Multisite Support </b> - The multisite system has been
completely redesigned and is now compatible with both URL
Rewrite module and embedded Gallery 2. Multisite Gallery 2
refers to multiple independent sites using a single codebase.
</li>
<li>
<b> Localization </b> - The installer and upgrader can now be localized.
</li>
<li>
<b> Improved Installer </b> - The installer offers now a clean install option,

step to combat server timeouts.
</li>

it easier to create a new layout that mostly involves
building the tpl files, but still allows use of additional
PHP code for more advanced layouts.
</li>
<li>
Standard $user template variable now available in all views, which makes
it easier to customize content for guests, registered users or administrators.
</li>
</ul>
</li>
<li>
<b> Hotlinked image protection </b>

<h3>
Highlight of changes in Gallery 2 Alpha 4 (Nice Commits)
<span id="alpha4-toggle" class="toggle"
onclick="toggle('alpha4-list', 'alpha4-toggle')"> + </span>
</h3>
<ol id="alpha4-list" style="display:none">
<li>
<b> Upgradeable Core and Modules </b> - At long last we
support upgrading from one version of Gallery 2 to the next.
Unfortunately, this may not work reliably for all version
before Alpha 4, so we recommend that you reinstall Alpha 4
from scratch just to be sure.
</li>
<li>
<b> Module Uninstall </b> - You can now completely uninstall a
module and then delete it from your Gallery 2 installation.
</li>
<li>
<b> Installer Improvements </b>
<ul>
<li>
The interface for installing modules is now much easier to
use. It shows you all the modules and lets you select the
ones you want to install, and lets you repeat the process
as often as you like.
</li>
<li>
Added better instructions and examples for several steps
that were confusing (your user feedback at work!)
</li>
<li>
The installer now works on browsers that don't allow
cookies.
</li>
</ul>
</li>
<li>
<b> User Interface enhancements </b> - Some changes in our
main layout place the most important system links on top of
every page (Site Admin, Login, Logout, ...). This gives you
easy access to these commands. The sidebar has some improved
functionality, like a direct login form and some more details
on your cart and members (if those modules are active). This
is another step towards a "block" system where modules can
provide any amount of blocks of information to be placed in
the sidebar.
</li>
<li>
<b> Navigation </b> - It's now easier to navigate around Gallery.
Meaningful "back" links will bring you back to the last
visited pages, e.g. it's now possible to visit the Site Admin
while editing an album and have an easy way to return.
</li>
<li>
<b> Random Highlight </b> - New module allows albums to
periodically change highlight, selecting randomly from
the album's items.
</li>
<li>
<b> WebCam </b> - New module creates items that
periodically refresh the image from an external URL.
</li>
<li>
<b> Thumbnail Page </b> - New module gives more control
over thumbnails for movies and documents. For multipage
documents (like PDF/Postscript) or images (like multiscene
TIFF) you can pick the page number for the thumbnail (Note:
PDF/Postscript require both ImageMagick and Ghostscript).
When used in conjunction with the Ffmpeg module you can
pick a time offset for generating thumbnails for movies.
</li>
<li>
<b> Graphics Toolkits </b> -
<ul>
<li>
The ImageMagick and NetPBM toolkits have been optimized
to make fewer calls to external binaries when used for
multiple operations. For example, cropping and resizing
to make a thumbnail now requires only a single call to
"convert" with ImageMagick.
</li>
<li>
We now preserve extra operations (like crop settings) on
thumbnails when moving an item between albums or
rebuilding thumbnails.
</li>
<li>
Added ability to set toolkit priority. This means you
can activate multiple toolkits to support more mime types
but still select which toolkit is used in cases where
multiple toolkits support the same type.
</li>
<li>
Added support for ImageMagick 6.1.x
</li>
</ul>
</li>
<li>
<b> Sort Order </b> - "Default sort order" and "Manual sort
order" are now separate choices, allowing albums to properly
inherit the site default for sort order; Ascending/descending
is disabled for these choices.
</li>
<li>
<b> New Items </b> - New module shows "new" and "updated"
images next to appropriate images and albums, and adds a new
sort where new items are shown first followed by other items
sorted by view count.
</li>
<li>
<b> SMTP Authentication </b> - We now support sending email
via a SMTP server that requires user authentication. Any
module that sends email (like the registration module) can
take advantage of this support.
</li>
<li>
<b> Embedding Gallery 2 </b> - We've made great improvements in
embedding Gallery 2 into other applications. We've
successfully (though not completely) embedded it into Xaraya
and have begun working on other platforms. See
<a href="http://codex.gallery2.org/Gallery2:Embedding"
target="_blank">Gallery 2 Embedding</a>.
</li>
<li>
<b> Thumbnail Creation </b> - We now let you create thumbnails
at upload time, which greatly improves performance the first
time you view an album. It's optional, but on by default.
</li>
<li>
<b> Improved Error Pages </b> - We now show you a nice error
page when two simultaneous and conflicting changes happen.
This new page explains how to resolve the problem.
</li>
<li>
<b> Members </b> - We now show a list of the recent
changes that a user has made, and let you page through the
entire list of changes.
</li>
<li>
<b> Removed IE7 </b> - We were experimenting with
<a href="http://dean.edwards.name/IE7/" target="_blank">IE7</a>,
a compatibility layer in JavaScript reduces some of the
incompatibilities between IE6 and other browsers. However we
were not able to get the performance and reliability that we
needed so we've decided to abandon using it (at least for now).
</li>
<li>
<b> Localization </b> - Gallery 2 is now translated into 18 languages, though only
German, Danish and Swedish are over 50% translated. We can
use your help!
</li>
<li>
<b> Bug fixes </b> - Many bugs closed!
</li>

<b> Watermark Support </b> - We now support image
watermarking. You can add a watermark to the thumbnail,
resize or full sized version of an image using a DHTML
drag-and-drop interface.
</li>

<b> Oracle Database Support </b> - The installer now offers
Oracle (version 9i and higher) among the supported database types.
</li>
<li>
<b> Module Manifests </b> - All modules now come with a
manifest file, and the installer checks to make sure that
you&rsquo;ve got a complete set of files on the server.
</li>
<li>
<b> Auto Completion </b> - the Site Admin user and groups
pages, and the permissions pages now perform appropriate
completion for you. Just type a few characters of the
username you&rsquo;re searching for and it&rsquo;ll give you up to 10
possible matches. Tested on Firefox, but not extensively
tested on IE yet.
</li>
<li>
<b> New version of IE7 </b> - We&rsquo;re experimenting with
<a href="http://dean.edwards.name/IE7/" target="_blank">IE7</a>,
a compatibility layer in JavaScript reduces some of the
incompatibilities between IE6 and other browsers. The older
version caused weird problems with images getting overlaid
with a red X, or IE6 crashing.
</li>
<li>
<b> Migration improvements </b> -
<ul>
<li>
We now properly migrate item owners
</li>
<li>
We now preserve the order of imported subalbums
</li>
<li>
Gallery 1 summary and description fields are now
transposed on import so that the Gallery 1 "summary"
(which was shown inside the album itself) is now the
Gallery 2 "description" and vice versa.
</li>
</ul>
</li>
<li>
<b> CMS Integration </b> - Although this is not yet readily visible, a
great deal of work has been done on getting Gallery 2 ready to integrate into
external content management systems. We&rsquo;ve successfully done partial
integrations with <a href="http://www.xaraya.com/" target="_blank">Xaraya</a> and
<a href="http://www.drupal.org/" target="_blank">Drupal</a>, with more on the way.
</li>
<li>
<b> Square Thumbnails </b> - We fixed a noticeable bug where
the first time you viewed a square thumbnail it might appear
distorted (this was mentioned in the "known bugs" list of the
alpha-2 release).
</li>
<li>
<b> Zip Cart Plugin </b> - You can now download the contents
of your cart as a zip file.
</li>
<li>
<b> User Albums </b> - You can use the new User Albums module
to automatically create a new album for a user whenever you
create a new user.
</li>
<li>
<b> Installer </b> - Many minor tweaks including adding more
install checks to make sure that your system is OK.
</li>
<li>
<b> Members </b> - The members module now has privacy settings
so that you can prevent the unauthorized from seeing your list
of members, and/or their email addresses.

<b> Performance </b> - Significant performance increases in
general, and especially for image views. This also reduces
the overall load on your system when (for example)
viewing a page with 9 thumbnails on it.
</li>
<li>
<b> Installer </b> - The installer now installs the core
module for you, as well as allows you to optionally install
other modules right away instead of having to do it later via
the Site Admin.

<li>
<b> Custom Fields </b> - New custom field module allows you to
define global and per-album custom fields for your item meta
data.
</li>
<li>
<b> Java Upload Applet </b> - New upload option where you can
drag and drop files onto an applet and Gallery 2 will upload them for you.

UTF-8 as part of the migration. We now also track where your
Gallery 1 albums wound up in Gallery 2 so that you can create
an .htaccess file in your Gallery 1 to redirect Gallery 1 URLs
to Gallery 2, for ease of migration.

<b> First Release of Gallery 2! </b>
</li>
</ul>
<h2><a name="packages">Choosing a package</a></h2>
<p class="toc-link"> <a href="#toc">[table of contents]</a> </p>
<p>
You can choose from four different packages:
</p>
<ul>
<li>
<b>Minimal</b> - The base application, 2 themes and 3 graphics toolkits.
Everything you need to publish photos, and nothing more.
</li>
<li>
<b>Typical</b> - The base application, 8 themes and a selection of popular
modules. Enough to satisfy the demands of most Gallery users.
</li>
<li>
<b>Full</b> - The base application, 9 themes and 68 modules. Every cool
feature we've got.
</li>
<li>
<b>Developer</b> - Same as the full package, except it includes all the
developer tools so that you can work on improving the code.
</li>
</ul>
<p>
You get to pick and choose which modules you activate, so even if you download
a package that has more modules than you need you can always choose not to
activate the ones you don't want. You can also activate a module and test it
out for a while, then later deactivate and uninstall it. You can also delete
any modules/themes that you're not using if you want to save space.
</p>
<p>
All of our modules and themes are available separately so if you install a
smaller package you can still add more functionality later on, either by
downloading yourself or using the new Downloadable Plugins feature in Gallery 2.2.

<li>
<b><a name="get_latest_code">Latest Version</a></b> -
There are four ways to get the code.
<ul>
<li>
<b>Tarball</b> - You can download a prepackaged file as a
tarball or a zip file from <a href="http://sourceforge.net/projects/gallery/"
target="_blank">SourceForge</a>.
</li>
<li>
<b>Pre-Installer</b> - If you only have FTP access to your webserver and don't
have the option to extract zip or tar files directly on the server, you should
give the <a href="http://codex.gallery2.org/Gallery2:Preinstaller"
target="_blank">Gallery 2 Pre-Installer</a> a try. It transfers the archive
directly to your webserver and extracts it for you.
</li>
<li>
<b>Nightly Snapshot</b> - You can download a tarball or zip file with
a snapshot of the most recent code. Find links to these on the
<a href="http://gallery.menalto.com/downloads"
target="_blank">Gallery Download Page</a>.
</li>
<li>
<b>Subversion</b> - This is a better way to get the latest code,
but it&rsquo;s for <i>advanced</i> users. Follow the
<a href="http://codex.gallery2.org/Gallery:Using_Subversion"
target="_blank">Subversion instructions</a> to obtain the latest Gallery 2
code. It&rsquo;s easier to stay up to date with this method since
you can run one command and get the latest code at any time.
</li>
</ul>
</li>
<li>
<b>Storage</b> - Create a directory for gallery to store
photos. This must be writeable by the web server, but for
security reasons we suggest that you do not put it in the web
root. If you put it in the web root, then anybody can get
directly to your images with their web browser which
circumvents Gallery 2&rsquo;s security.
<div class="instructions">
<h3>Unix Example</h3>
<p>
$ cd $HOME <br/>
$ mkdir g2data <br/>
$ chmod 777 g2data
</p>
</div>
<div class="instructions">
<h3>Windows Example</h3>
<p>
C:\&gt; mkdir g2data
</p>
</div>
In the Unix example, you may note that modes of 777 on your
<strong>g2data</strong> directory are not all that secure.
However, making it more secure depends on how your system is
configured. Talk with your system administrator about ways to
change the permissions on that directory to make it so that
Gallery can still write to the files but that others
can&rsquo;t. Refer to the <a
href="http://codex.gallery2.org/Gallery2:Security">Gallery
2 Security Guide</a> for more information.

<b>Database</b> - Right now we support
<a href="http://dev.mysql.com/downloads/" target="_blank">MySQL</a>,

<a href="http://www.microsoft.com/sql/" target="_blank">Microsoft SQL Server</a>.
The databases most commonly used with Gallery 2 are MySQL and PostgreSQL.
MySQL is generally faster than PostgreSQL.
We require you to create the database yourself.
In our examples below, we&rsquo;ll be creating a database called
<b>gallery2</b>. You can use any database name that you
choose. <br />
Grant all required <strong>privileges</strong> to your database user. This includes but
is not confined to: CREATE TABLE, ALTER TABLE, DROP TABLE in the gallery2 database;
SELECT, INSERT, UPDATE, DELETE on all (gallery2) tables in the gallery2 database;
CREATE INDEX and some other privileges that are specific to the different database
management systems. CREATE/DROP DATABASE and the ability to GRANT privileges to other
database users are not required.

<b>Graphics Toolkits</b> - Gallery 2 works with many different
toolkits (<a href="http://netpbm.sourceforge.net"
target="_blank">NetPBM</a>, <a
href="http://www.imagemagick.org/"
target="_blank">ImageMagick</a>, <a href="http://php.net/gd"
target="_blank">GD</a> or <a
href="http://www.graphicsmagick.org/"
target="_blank">GraphicsMagick</a>). You need to activate at
least one or you won't get any thumbnails, but there's no
limit on how many you can have. In fact, more is better
because they can work together. Here are some interesting
points about the main supported toolkits (mostly reported by
users, your mileage may vary).
<ul>
<li>
<b>Fastest</b> - ImageMagick and GraphicsMagick
</li>
<li>
<b>Highest Quality</b> - NetPBM (ImageMagick is a close second though)
</li>
</ul>
Limitations:
<ul>
<li>
<b>GD</b> - cannot do image rotation, may hit server
memory limits and crash PHP.
</li>
<li>
<b>NetPBM, ImageMagick, GraphicsMagick</b> - require server to support exec() system
call (not usually a problem)
</li>
</ul>
</li>
</ol>
<h2><a name="installing">Installing</a></h2>
<p class="toc-link"> <a href="#toc">[table of contents]</a> </p>
<p>
Gallery 2 is a web application and must be installed on your web
server in order for you to use it. If you've unpacked it on
your desktop, you will have to upload it to your server as part
of the install process. Then you can configure it using your web browser.<br/>
As an alternative to the lengthy upload via FTP, take a look at the
<a href="http://codex.gallery2.org/Gallery2:Preinstaller"
target="_blank">Gallery 2 Pre-Installer</a>.
</p>
<ol style="margin-top: 0.2em">
<li>
<b> Upload </b> - Copy the Gallery 2 files to a directory on your webserver. There are
several alternatives for this step:
<ul style="margin-top: 0.4em; margin-bottom: 0">
<li>
<b>Fastest way</b>: Upload the gallery package to your web
server archive via FTP or another method, then unpack it
using an interactive shell session (e.g. ssh or telnet).
Example unpacking commands (choose the appropriate one):
<div class="instructions">
<h3> For .tar.gz archives </h3>
<p>
$ tar xzf gallery2.tar.gz
</p>
</div>
<div class="instructions">
<h3> For zip archives </h3>
<p>
$ unzip gallery2.zip
</p>
</div>
If you do not have shell access, you can ask your provider
to do it for you, or you can make a miniature PHP script
containing one of the above commands. Some webhosting
companies offer a control panel with a web file-browser
which is capable of extracting / unarchiving archive
files. It&rsquo;s worth a try to check if this option is
available.
</li>
<li>
<b>Easiest (but slowest) way:</b> If you don't have shell
access, you can upload the complete contents of the
Gallery 2 archive to the webserver with an FTP
program. This may take a lot of time and be
error-prone. In this case, pay special attention to the
&rsquo;System Checks&rsquo; step of the installer and make
sure that there are no missing or modified files.
Consider using a smart FTP program like
<a href="http://filezilla.sourceforge.net/" target="_blank">FileZilla</a> to
make sure that your transfer goes smoothly.
</li>
<li>
<b>Advanced way</b>: The best way to install Gallery
<b>and</b> stay up to date if you have shell access to
your webserver is to use
<a href="http://codex.gallery2.org/Gallery:Using_Subversion"
target="_blank">Subversion</a>.
</li>
</ul>
<b> Note: </b> After uploading, you should close this version
of the README and browse to the version that you just
uploaded. That way all the links in this document will point
to the right places in your Gallery 2 install.
</li>
<li>
<b> Begin Installing </b> - Open up your web browser and browse to the
<a href="install/index.php" target="_guided">install directory</a>.
Gallery 2 will walk you through the process of validating that your system
is properly configured and will set everything up for you.
</li>
<li>
<b> Authenticate </b> - You will be asked to create and save a
small text file in order to authenticate. You may not proceed
until you do this. That&rsquo;s how Gallery 2 knows that you&rsquo;re authorized
to use the installer.
</li>
<li>
<b> System Checks </b> - The installer checks your system to
make sure that it will support Gallery 2. Make sure that all
checks are successful!
</li>
<li>
<b> Installation Type </b> - Gallery can support multiple independent sites with
a single installation of the code. Here you will select a standard single install
or the location of a new multisite install. There is more information about multisite
in the <a href="http://codex.gallery2.org/Gallery2:Multisite"
target="_blank">Gallery Codex</a>.
</li>
<li>
<b> Storage Setup </b> - Read the instructions on the
installer to set up a storage location for Gallery 2. This is
where Gallery 2 will store all of your images, as well as other cache
information.
</li>
<li>
<b> Database Setup </b> - Select your database type and enter
your database authentication information. If this is not your first Gallery 2 installation
and there are still some remains of the old installation, it will check the state of the
installed version and offer a clean install option which will delete all your data in the
storage directory and in the database. If the installed version seems to be fine, it will
also offer to reuse the existing database tables. Select this option if you did not start
the installer with the intent to start from scratch.
</li>
<li>
<b> Admin User Setup </b> - You are prompted for an
administrator username and password. Type in a password and
type it again to validate it. The full name and the email address are optional.
But entering an email address is highly recommended. Once you&rsquo;re finished,
click &rsquo;Create&rsquo; to create the admin user for this installation of Gallery 2.
</li>
<li>
<b> Create Config File </b> - Gallery 2 will create the
<b>config.php</b> file in your Gallery 2 directory. This contains
all the answers you&rsquo;ve provided in the installer and is
necessary for Gallery 2 to function properly. At this point, there&rsquo;s also a sanity
check to prevent you from damaging your Gallery install by running the installer when you
should rather have started the upgrader.
</li>
<li>
<b> Install the Core module </b> - Here&rsquo;s where we create all
the database tables and initial users and albums to get you
started. Unless something goes wrong, there&rsquo;s nothing for you
to do here.
</li>
<li>
<b> Install other modules </b> - Gallery 2 has lots of different
modules that provide useful functionality. Choose which ones
you want to use. You can always go to the <a href="main.php?g2_view=core.SiteAdmin"
target="_guided">Site Admin</a> page later on to install, activate, deactivate or
uninstall modules, so it&rsquo;s ok to experiment here.
</li>
<li>
<b> Check Security </b> - Gallery 2 walks you through the process of
locking down your new <b>config.php</b>.
</li>
<li>
<b> Finished! </b> - Congratulations! You have successfully
installed Gallery 2!

</p>
<div class="important">
<h3> Warning When Upgrading from Gallery 2.0! </h3>
<p>
Third party modules and themes designed for Gallery 2.0 will
not work with Gallery 2.2. During the upgrade process, these
modules and themes will be automatically deactivated for you.
You can find updated versions for most of these modules and
themes here: <a
href="http://codex.gallery2.org/Gallery2:User_Contributions">http://codex.gallery2.org/Gallery2:User_Contributions</a>
</p>
</div>
<ol>
<li>
If you have a busy site, consider putting your Gallery in
maintenance mode before updating the code and performing the
upgrade. This gives visitors a message that the site is
temporarily offline, rather than showing everybody the upgrade
page. Edit your config.php file to activate maintenance mode.
This feature is new starting in 2.1, so it is not available in
an upgrade from 2.0.x.
</li>
<li>
Download the latest code for any active third party modules
that you're using, or deactivate them. If in doubt,
deactivating is safe.
</li>
<li>
<a href="#get_latest_code">Get the latest code</a> and unpack
it over your existing copy of Gallery 2. Keep your existing
config.php in place, and don't touch your (g2data) data folder
or the database. If you're using Subversion, you can just do
"svn update" at any time. Alternatively, you can also use the
<a href="http://codex.gallery2.org/Gallery2:Preinstaller"
target="_blank">Gallery 2 Pre-Installer</a> to get the latest code
onto the webserver.
</li>
<li>
If you use a PHP accelerator / cache (e.g. Turk mmCache,
Ioncube PHPA, eaccelerator, Zend Studio, etc.), flush (clear)
the cache of the accelerator. Omitting this step can
<i>sometimes</i> lead to errors during and after the upgrade process.
</li>
<li>
Browse to <a href="upgrade/index.php" target="_guided">the
upgrader</a> and follow the instructions there. <b>Make a
backup of your data</b> (g2data folder and especially the
database) when it tells you to! Should you lose your data due
to a bug in the upgrader, the first thing we're going to tell
you to do is to restore from your backups! (Then we'll
probably ask you to help us reproduce the bug.)

Enjoy your new version of Gallery 2.
