This is a free site that will let you set up a rotating random image url -- for example, for a forum sig. It's still in kind of an advanced beta here... everything works fine, just that nothing's pretty yet, but I'm working on it. To get started, enter a username and password below. You don't have to sign up or anything. Just make up a username and password.
