Variant Image Penguin

Fairly good. Does exactly what you'd want and helps you assign images to product variants. Some features like 'Hover to Zoom' won't work because the zoom will pick up photos being hidden but, we just turned that feature in our theme customization off and it's made our website look a lot nicer and hopefully more user friendly.

Had some trouble getting it working, but their support was very helpful and got it up and running right away. Does exactly what we need it to, and really helps with making the product pages nice and clean. If this is what you're looking for, it seems to be the best option out there.

In the beginning it didn't work but on mobile but after contacting the support they solved the problem and now it is working perfectly
