Stories abound of pictures being ‘borrowed’ from online family albums or Facebook for various fraudulent purposes. There was the Massachussetts mother who found their child’s photo on a Craig’s list adoption scam and numerous cases of unauthorized uses of photos in advertising campaigns. The privacy settings on your social networking site or image sharing site will go a long way to limiting who can access you photos in the first place. Ideally, keeping the list to a minimum known set of friends will protect your photos from most nefarious uses. Another step that you can easily take to protect and identify your pictures is to use a low cost watermarking software package like iWatermark.
