FotoTagger

FotoTagger is a free software tool for annotating images and image areas quickly and easily, organizing images and grabbing them directly from browser. Place on an image movable annotation notes that point to individual elements visualized on the image. Mark notable details. Identify people and objects.
Display your tags in a form of balloons. Create image macros, talking pictures and books of comics from your photos. Comment specific objects. Instantly find a particular person, object, or comment among image collections.

Annotations do not change an original image so moving and sharing files keep annotations intact.
