@Hotclutch thanks for this question! Didn't plan a post on Sunday but am happy to share   So, product images in osCommerce v4: 1. You can have any number of images linked to a product. The only limitation is common sense and design restriction, if any.  2. When uploading images, the system will automatically resize them into a bunch of different sizes, used for different purposes - like Zoomed in, regular product info page, product listing, various boxes and smaller listings, etc.
