I have enabled multiple images for my products under Catalog --> Product Types --> Product - General. However, for only one of my many products I cannot get a second picture to display. I have tried mulitple times, using a naming convention and product setup similar to other products with no success. I also deleted a previous version of the product and redid the entire product upload for that product. Still no success - it is the only one of my products that I cannot get a second picture to show. Any suggestions?
