safa, thank you for your reply! Sorry about the late response. I have a lot of work going on. =o
Ok, I had found the reference to the image. It was attached to another image from another product. So I deleted the image from the referenced product in BO, and then the image switched to the 2nd image from that referenced product. This was really weird. So I deleted all the images from that referenced product, and once that was done, the problem was fixed! The item now uses the correct image!
Thank you so much for your help!! Take care!
