I have noticed an undocumented feature, which may be unique to me.

Regular images don't show in the product info display. If I don't add pictures with the Swapper, then no images display in the product. I add a single image to swapper and the image displays on the product info page. I tried playing around with else and if statements, but I'm not that talented.


And I have this mod working with:
SEO URLs
Image Handler
Column Grid
Stock by Attributes
FEC
Improved Attributes Controller


I had to tweak around some settings, but other than the image no showing on product info display without loading image into swapper, everything works great!
