Right, it's not working correctly. Signs and Symptoms.

IH2 is installed and appears to be working fine (it's thumbnailing images OK).

The medium image is loading correctly on the product page.

The Lightbox is loading fine EXCEPT it is NOT loading image_LGE it is loading the original image.

I have the Additional Image attribute set to true, except the additional images don't load either on the page itself OR on the Lightbox overlay (no next / prev buttons appear)

I've tried looking through to find the answer, but honestly, I'm not sure what I'm looking for and there is a LOT in here
