Hi Jay, I got it working. I deleted all the old image files in the folder, and it seems to have fixed it.

I do have one product that no matter what doesn't seem to be working:
Baby Treeson

This is the only product that I'm using with attributes. I have "Use Attributes" turned off in Image Swapper, as I want to use the same photos regardless of which attribute is chosen. Any idea how to get the images to work?

The other thing I'm noticing, I now have 2 "Add to cart" buttons. I don't remember having 2 before installing Image Swapper. What do I need to do to remove the bottom button?
