Hello, @Michele P,
I have debugged your site and deactivated the third-party plugins. After doing so, the variation gallery images are now working properly. I have also captured a video for you to view here: https://www.veed.io/view/2104e457-639c-4288-9aee-d28b5133b92e?sharingWidget=true&panel=share. Please clear your browser cache and check your site again.
For now, I have left all the third-party plugins deactivated on your site. Once you have checked and confirmed, you can reactivate them one by one and check which one is causing the issue on your site.
Best Regards,
8Theme’s Team
