Hi catseye. Yes. In Woocommerce tab, click Settings. Then select “Catalog” tab at top. At the bottom, there is a section called Image Options, which has a link to “regenerate your thumbnails”. Click this and install this plugin.
Once this is done, just regenerate all thumbnails and it fixed my issues. you may not notice it right away, but if you keep refreshing your website, the images should become clear after a minute or two.
Hope this helps!
