Fototagger
Cogitum
FotoTagger helps to annotate people and objects on your photos by adding easy-to-hide movable tags over pictures. Effective search helps to find specific notes, including names, in your picture collection. Caption and tags are embedded into your file, without changing the image; moving and sharing files keeps annotations intact; uninstalling FotoTagger will not change your pictures. FotoTagger works with JPEG files.
