Okay, to get the little picture under your name you need to first go the link to user cp (the same place where you entered the clip art into your text). Once you get there, you want to click on the link to "edit options", when that screen opens, scroll all the way to the bottom.
At the bottom of the screen there is a button (your last option) to "change avatar", this is what that little thing under your name is called. It will give you about 100 choices of avatars, or you can create your own custom avatar (I haven't tried that yet, if you figure it out, let me know).
After you've chosen, click submit modifications and your little picture should start working!
Hope that helped! Let me know if you need any additional help!
