The only photos I find creepy are of movies that are nearly 100 years old or older because of the unreal pancake makeup, etc. But family/childhood pictures don't creep me out. I wish I had my childhood pictures because it would be good to see who I was versus who I am. And as others said, remember the potential in life and in myself.

Edit: Well, actually Victorian photos creep me out, especially of dead children, etc. (They used to photograph their dead.)
