The ShopTab Facebook Store app can support up to 4 images in the product listing. They may be uploaded manually or via a data feed.
Once the images are loaded the buyer can click the image and see the image with the other image options as noted below.
These images may be added to your CSV data file with title fields of image_link_2, image_link_3 and image_link_4. If using an XML file, they will be image_2, image_3 and image_4.
