Sometimes a picture is worth 1,000 words too many. Watch those profile photos and photo albums. Remember, profile photos are always visible to search engines, so think twice before you swap your tasteful headshot with something amusing or potentially distasteful. Be careful of how much skin you're showing and, as always, be conscious of what message you're sending about yourself. Even conscientious Facebook users often overlook this issue.
Photo tagging is another dangerous blind spot. You never know when one of your friends will post an embarrassing or inappropriate picture with you in it, and then tag you so that the photo appears in the "View Photos Of…" list below your profile picture. Unfortunately, you cannot control who tags you in a photo, or who the owner of the photo allows to view it. You can, however, remove the tag entirely (only the photo owner and the tagged person have this ability). You might also want to set Facebook's notifications to tell you whenever someone tags you in a photo.
