Well I had some free time yesterday and decided to design and build a random avatar picker.
http://www.stelf.com/b63/ <-- is the avatar gallery, which is made up of some pictures I made into 90x75 avatars.
Works well on PHPBB boards or any board which allows you to use url avatars, to use either put 'http://www.stelf.com/b63/avatar.jpg' or 'http://www.stelf.com/b63/avatar.jpg?film' and place this info in 'Link to off-site Avatar:' which is found in profile.
If you don't specify a category it will randomly pick from the whole avatar gallery.
This will be running until a time where i'd have to cut it because of bandwidth usage.
