People post pics of themselves... However consider anonymity if that's important to you... I like to find artistic expressions that convey things I like to do... As you see I like to bicycle... In the winter I like to ski, so I have some avatars for then... I like to fish too, I may change my avatar for the fall... Hmmm... I guess I'd better google some images, LOL, haven't changed mine recently...
Dee74 does some cool things with his avatars...
