Hi Christian,
You are correct this is a limitation of the variant grid display type. The variant grid was not programmed to dynamically change the variant image the way the other variant display type options do (i.e. dropdown, radiobutton, etc).
You are also correct that the main product photo gallery is limited to 6 images.
Please see the following alternate solutions for you:
1. Configure your product variants to use one of the display types (i.e. dropdown, radiobutton, etc) that support dynamically changing the variant image. This will allow you to configure a product to display an unlimited number of variant images.
2. You can use one of the 5 tabbed html product descriptions to display a gallery of all your product flavor images
3. We can program the variant grid to work with variant images to dynamically change the main product image with the variant image with the appropriate variant is selected in the grid.
4. We can program the main product photo gallery to support additional images so you can display pictures of all your product flavors.
Items 3 and 4 require programming changes to the cart, if you would like to move forward on either of these items please submit a quote request using the following link:
