Akin to a creeper, but caught on film! A photo creeper is a completely random person in the background (or foreground, if you're really lucky) that ruins a picture--or enhances is, depending on your viewpoint.
"OMFGZ! Like, this would be such a good picture of me and my girlies if there wasn't some random drunk bro in the background, like, creeping on us! What a photo creeper! ROFL!"
