Hi Amber,
Sorry that you’re having a bit of trouble with the lightbox feature. I just tested it and it seems to be working correctly. So I think there is probably either a conflict or incorrect setting specific on your end that is causing an issue. A couple things to try:
– I noticed that all your image file names have the image size on the end? Is there a reason for this? Do you have some kind of plugin that is automatically cropping or resizing images? If so, please try deactivating it. Also, try using images that don’t have that at the end and are the full-sized original images.
– Also, if you have Thumbnail Support enabled in our plugin, then please try disabling it to see if it makes a difference.
– Also, try one of the other product page layouts (such as tabbed or shop style) to make sure it isn’t a specific conflict between your site and that one layout.
– Also, try creating a brand new product and only uploading the main image. Does it still show a duplicate, or is just with the additional images?
