you probably should not use gimp.  you could probably code a python or perl 
module for gimp, but that would be sort of overkill.  i would reccomend 
installing imagemagick and reading the man page for convert.  messing with the 
names would require some clever bashing.  i've done it all before, with cygwin 
and win32 convert no less, on 300 images or so, but i don't remember offhand 
what commands i used :)

good luck, let me know if you just can't freaking figure it out and i'll see if 
i have anything in my bash history at work.
