The Finer Points of Facebook - #6 - Keep Your Facebook Photos Private
Facebook allows you to share as much or as little detail about yourself as you like. Most of us are careful and don't upload questionable, racy or potentially embarrassing photos to Facebook. However, we can't count on our Facebook friends to show the same discretion. If a friend uploads a photo you're in but would rather not be associated with, you can easily untag Facebook photos so your Facebook friends won't likely see. You can also choose to set all Facebook photos of you to private.
