Depends on your images but you might get away with the old divide-scanned-images
script. There are various enhanced versions but the original is worth a try.

Usually as its name, split up a page with several images but a single image
works.

Can be used individually or in a batch mode. Quick video demo, duration 2
minutes, using the batch function.
