Facebook photos are very popular. Facebook photo usage rivals the dedicated photo sharing sites. Facebook announced this week that it will make it easier than ever to identify friends in photos uploaded to Facebook by using facial recognition software to suggest people to tag.
Sounds like a much easier way to inventory photos. However, if you don't want YOUR name suggested on other profiles when they upload photos, you have to turn YOUR privacy settings for this feature off.
Otherwise, pictures of you at the neighbor's costume party might be tagged with your name for your co-workers to see!
