Howto Random Images

From LinphaWiki

If you don't save this code into a file in the the linpha directory, you have to edit $linpha_dir variable, for example $linpha_dir = './linpha';
If you access this file without parameters the random images are taken from all available folders but you can also access this script with the parameter album, for example:
random.php?album=album1
Which, as a result will only show random images from album1
