I allways see people with diferent pictures and no one with that boring pictures that Xbox live have... Please help me Thanks!!!
The only way to have a custom gamerpic is if you have a Vision Cam but even then only people on your friends list will be able to see it.
Got a female friend on my list that puts this to good use, if you know what i'm saying. :D its like the milk man comes everyday.
But what voteDC said, vision cam.
There's also a few poses you can get by using the xbox.com site and editing your avatar that you can't on the dashboard & visa versa .
You can download every free gamerpic pack you see to try to vary it a bit.
(Sorry that the link isn't "live", the new Anchor dialog is confusing me.)
