mtlfloss, are you wanting more images per product page? If so, IH isn't designed to do that. It's designed to show one image place holder, with up to 3 different images:
1: default image on your home page
2. Larger image (which can be different image, or same image), upon hover of 1st image. This image will also be the one to show on the product page.
3. An even larger image upon click of 2nd image, which can still be the same image, or a different larger image.

But not to show all 3 on the same page.
