|
// My modification adds support for multiple avatar galleries using a
|
|
// drop-down list. Selecting a gallery in the drop-down list changes the
|
|
// images available to the user.
|
|
//
|
|
// Default Gallery is your normal SimpleBoard /gallery/ folder. Any images
|
|
// directly in that path will be displayed in the Default Galllery. To add
|
|
// galleries, just create sub-directories. Whatever the subdirectory is
|
|
// called will be the name of the gallery.
|
|
//
|
|
// It's pretty simple. Just replace your avatar_upload.php with this one.
|
