A while back I had someone build me a script that allows the site owner to upload products to the site. Its not an ecommerce site since you can't buy anything online. With each product added there could be 1 image with it. Now we would like to be able to add at least 4 images with each product. When you click on the image a popup appears so you can see the larger version like it currently does.
Attached is a rough idea of how I'd like the additional 3 images to be displayed below the primary image for the product.
