There are three steps you need to follow to create multiple images for products:

1. Assuming the product is already created, else Create ( Add ) the product  [Admin: Add Product]


2. Locate this product, Edit it, then go into the "Images & Video" tab.   [Admin: Product Manager]


3. Remember when adding any additional images other than the main image, set the status of additional images too "Additional Image"


You will then see the "Additional Status" value next to the image once uploaded.


NOTE: All product images must be below 250kb in file size, and their dimensions preferably set too 600px by 600px.
