Lazy load images
I have up to 10-15 images per variation and woothumbs loads them all at once. Loading only 1 or 2 first images and then loading rest of images would greatly improve user experience for all users. Additionally google mesures loading time of largest elements that user sees on page (Largest Contentful Paint (LCP)) and image gallery is the largest content. So adding lazy loading images woud upon improve google site rating.
