For my profile I can get a pic for my photo and my signature, but I don't know how to get one for my avatar. I didn't see an option to link one or anything like that. It only shows the drop down list of avatars. So how do I get my own avatar pic??? (Biggest noob question in the world by the way.)

Also, I want some really cool pics but are the pixels are too big in dimesion. And I can't find any smaller ones online. I can crop it when I save the pic and load it in painter or something like that but then I can't use it 'cause it has to be a pic from online. How do I fit my pics that I want into my signature/photo/avatar???
