Facebook allows users to upload images to photo albums. By default, your Facebook friends can see all the images you upload and search through your albums. You hide images changing the privacy settings of the album in which they are. Your Facebook photo albums may be private (only you), hidden from all but specific friends or hidden to specific individuals. Each image uses the privacy settings of the album that is, the images do not have their own privacy settings.
