// this plugin for accessing Gallery2, this is where you'll need
// to validate that your ebedded page exists and then get the values from your
// embedded application $g2ic_gallery2_path, $g2ic_gallery2_uri, and
// $g2ic_embed_uri.  Descriptions of these variables are in config.php
//
// You'll also need to set $g2ic_embedded_mode to TRUE.
//
// If you use the full directory path for $g2ic_gallery_path, you'll need to set
// $g2ic_use_full_path to TRUE.  If you use a path relative to the root web page,
// you'll need to set $g2ic_use_full_path to FALSE.
//
// If your embedded application sets its own localization, you'll need to set the
// language in $g2ic_language.  If you need to load the language file for any
// initialization messages (as in the WPG2 code above), you'll need to load it
// before those messages appear.  If you do load it in your initialization
// sequence, set $g2ic_language_loaded to TRUE, so that the language pack won't
// get loaded again.
