Hi @emtree
If I understand you correctly, you would like the product gallery images to not change when selecting a variation of the product, right?

This would need customization to do it since this is the expected behavior especially if the variation has its own image like here:

In this case, what you want to achieve is a bit complex and would require customization to do it. Since custom coding is outside our scope of support, I am leaving this thread open for a bit to see if anyone can chime in to help you out.
For questions related to development and custom coding, your best bet is to ask on any of these channels for support. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there, too.
– WooCommerce Developer Resources Portal
– WooCommerce Advanced Facebook group
– WooCommerce Community Forum
– WooCommerce Developer Slack Channel.

Hope this helps!
