I just saw ur status...
Well to change your profile pic and to update your "About me" section and all, here's what you can do..
At the top you can see the "Fan gallery" banner. Where it shows how many fans do u have and how many you have fanned.
Just beside that to your left you'll see "Edit profile" Button in blue. Click that.
When the page opens, you'll see on your right, a banner called "Design". Under that you'll see "Profile picture" and "Background picture". Just click on "change" and you can upload the pic you want as ur proflie or background pic from ur computer....
Hope that helped!
