25 * Display an album of a set of photos with optional descriptions.
27 * @author: Ted Vinke <teddy@jouwfeestje.com>
28 * Reini Urban (local fs)
29 * Thomas Harding (slides mode, real thumbnails)
33 * src="http://server/textfile" or localfile or localdir
34 * mode=[normal|column|row|thumbs|tiles|list|slide]
40 * align=[center|left|right]
44 * "src": textfile of images or directory of images or a single image (local or remote)
45 * Local or remote e.g. http://myserver/images/MyPhotos.txt or http://myserver/images/
46 * or /images/ or Upload:photos/
47 * Possible content of a valid textfile:
48 * photo-01.jpg; Me and my girlfriend
50 * christmas.gif; Merry Christmas!
52 * Inside textfile, filenames and optional descriptions are separated by
53 * semi-colon on each line. Listed files must be in same directory as textfile
54 * itself, so don't use relative paths inside textfile.
56 * "url": defines the the webpath to the srcdir directory (formerly called weblocation)
61 * - specify picture(s) as parameter(s)
62 * - limit amount of pictures on one page
63 * - use PHP to really resize or greyscale images (only where GD library supports it)
64 * (quite done for resize with "ImageTile.php")
67 * - reading height and width from images with spaces in their names fails.
69 * Fixed album location idea by Philip J. Hollenback. Thanks!
