So I don't know if this is a setting or something I am doing wrong but here is what is happening.
on our product page, I have multi-images working for the most part. When you go to the product detail page, it shows a product image with thumbnails underneath. When you rollover one of the thumbnails it shows that image where the product image was.
The problem is that it will not revert to the original product image that shows before you did the rollover.
I am using V9.1.0.1 multistore with product.simplevariantformat.xml.config
