on the top of your screen it says ...Welcome back ___ | Fun Mail | Questions | Advice | My Photos | Logout.
Click where it says My Photos.
once your there click "upload(or add) a photo" I dont remember exactly what it says. find your photo add a caption and then you have your photo!
up in the top of your screen, it should say "Welcome back," and your "manthy" as a link. Click on it. When you see your homepage, there should be a sort of menu of links on the left. Click on "My Photos" and there should be a link that says "Add Photo." I think you know the rest. =]
