Your not likely to find a program to perform that very specific task. In other words, if you want better performance, write it yourself.

IIRC, there is a very mighty batch-process feature in Photoshop to do tasks like this...

IIRC, gimp has a plug-in that will subdivide an image into multiple images for your. If not, writing some script-fu for the job shouldn''t be that hard.

...this looks like the perfect training excercise on loading images, and saving subimages...

IIRC, this can be easily done programatically using DX (even Win32).. if course if you have premade apps, this is a moot point. Sorry for thinking outloud, or should I say, thinking through my fingers..

You can probably just write your own program in a couple of lines if you use a good image library to handle the grunt work for you. For instance, I wrote a similiar program that goes through a bunch of bitmaps and converts them to JPGs and then makes a thumbnail of the image, just using FreeImage, and it only ended up being about 50 lines or so (and most of that was just code to get directory listings and such).
