Do you want an avatar (the picture under your name)? I wasn't sure which pictire you were talking about.
If you do, go to "my profile" at the top of your page, click, then click on "view/update" inside,
then go to "Select Avatar" and a whole bunch of pictures will come up and when you see one you like, click on it, then before you exit, click on "Update Profile" at the bottom.
Good Luck.
