When I click on the thumbnails of images below the default one the popup for the images is blank. I am using directResize but as far as I can remember this was happening even before I used it. I have a screen attached incase I am unclear about where this is happening.
I have one of the images set to be the base, small and thumbnail and they show up fine in the category and as clickable thumbs. Only the main image popup is blank. Any and all help is greatly appreciated and let me know if I need to provide more info. Thanks!
