When a someone posts a photo on Facebook, the photo recognition software tags friends in the photo with names that Facebook thinks match the faces. This is a great feature in iPhoto but creepy in Facebook. You can untag yourself in any photo but if you want to stop it happening at all you need to change your privacy settings.
