Also see the override directory postings in the forum/FAQ. The above are suggestions, incorrectly applying them could cause harm to your site, Backup, backup, backup and test before using on your live site.
Oh yeah, the other thing could be that the template is not properly calling images; however, it does appear that the bmz_cache is being used, so to some extent iH is being used/called.
As for images on the products, only additional images would be enlarged (compared to a base ZC install) as the image displayed for a product is a medium image and as explained in the documentation, medium images are not resized. (History as to why is in this thread and elsewhere.)
