/**
 * Display an album of a set of photos with optional descriptions.
 *
 * @author: Ted Vinke <teddy@jouwfeestje.com>
 *          Reini Urban (local fs)
 *          Thomas Harding (slides mode, real thumbnails)
 *
 * Usage:
 * <?plugin PhotoAlbum
 *          src="http://server/textfile" or localfile or localdir
 *          mode=[normal|column|row|thumbs|tiles|list|slide]
 *          desc=true
 *          numcols=3
 *          height=50%
 *          width=50%
 *          thumbswidth=80
 *          align=[center|left|right]
 *          duration=6
 * ?>
 *
 * "src": textfile of images or directory of images or a single image (local or remote)
 *      Local or remote e.g. http://myserver/images/MyPhotos.txt or http://myserver/images/
 *      or /images/ or Upload:photos/
 *      Possible content of a valid textfile:
 *     photo-01.jpg; Me and my girlfriend
 *     photo-02.jpg
 *     christmas.gif; Merry Christmas!
 *
 *     Inside textfile, filenames and optional descriptions are seperated by
 *     semi-colon on each line. Listed files must be in same directory as textfile 
 *     itself, so don't use relative paths inside textfile.
 *
 * "url": defines the the webpath to the srcdir directory (formerly called weblocation)
 */

/**
 * TODO:
 * - specify picture(s) as parameter(s)
 * - limit amount of pictures on one page
 * - use PHP to really resize or greyscale images (only where GD library supports it)
 *   (quite done for resize with "ImageTile.php")
 *
 * KNOWN ISSUES:
 * - reading height and width from images with spaces in their names fails.
 *
 * Fixed album location idea by Philip J. Hollenback. Thanks!
