software to automatically chop a photo into smaller images

I want to make a mosaic image from a collection of other images, but I
don't have enough images for the mosiac to work properly. So, instead
of reducing the size of the other images into mosaic "tiles", I'd like
to try chopping them into smaller bits of each image. I'm looking for
software that will take a folder of source images and automatically
create smaller images based on input parameters. Freeware would be
nice. :-)
