All this sounds as if you are trying to do that on your "real" images?
Hopefully you have a backup, because if you do anything wrong here,
you could destroy all your images!
(in particular, you are going to wipe all the exif
information, including date, shutter speed, aperture etc. etc.!)

Because of this, I would recommend to test this out
with a limited set of images and try to isolate the problem
so that there is a chance to find out the real source of the problem.

Best, Arnd

P.S.: I know that I did not answer your question,
this was on purpose ;-).
You could use find, together with exec, see eg.
For more complicated loops:

(Warning repeated: if you do something wrong here,
you might ruin your images ...)
