I am looking for a way to draw multiple boxes around parts of an image at one time (sort of a ctrl+select) then save each box as a separate image. I usually use GIMP for photo editing, but any free software would work.
For example, in the following image named "birds.jpg", I would like to draw a box around each individual bird then save each of the three boxes as separate images named "birds1.jpg", "birds2.jpg", and "birds3.jpg". I can crop/save as/undo multiple times, but some images have 20+ boxes to cut and there are hundreds of images. Any plug-in that may do this? Other ideas? If this question belongs elsewhere please let me know.
