Adding multiple images in the same tag is visually very appealing and can help you with proper product displays and variations.
Once you've added an image in your Material Library, you can start by adding it to your scene.
1. Select Image Tag in the menu on the left, select the tag in your media library and place it in your scene.
2. Now select your tag and click on Image Settings in the menu on the right. Under Thumbnail you can upload the image that will be visible in your scene. Under Product Page Images you can upload up to 5 images that are shown in the pop-up window. The images are shown in the order that you've uploaded them.
Make sure to click Save when you're done!
