Under "Features" on your left, go to "Fan Photos." Upload them to your fan photo album. Then right click on the pic, and post the link where it says "Optional Image" when you are making a post.
FYI, my fan album did not appear right away, so yours might not either. Also, if you right click on a picture, a pop-up will, well, pop-up, but just click "Okay" and you should choose "Copy Image Location" or however it appears.
