im not sure, but my guess would be that since the avatars can be .gif format that you could just use an animated gif file. you can make your own using many different programs available on the internet. try download.com to find one.
If you ask real nice, one of the members may help you animate it. Cyclone2 animated mine.
I need to learn how to do animation using Phtoshop. (Paintshop Pro too!)
If you is animated, how come you are not doing a jig, or hopping at least ?
And what's with the arms lieing still, the head not turning, and doing "the Monkee" or at least the "Frug" ?
Thanks for the suggestions Doogie. But I just wanted some subtle animation to my avatar. I didn't want his arms and legs flailing about like he was some kind of spazz!
(Allthough, it does sound kinda funny once you think about it!)
Moving body parts is a lot more difficult than other animations. You'll notice that mine is really just transitions, not actual motion. BTW, mine was done in Paint Shop Pro.
