I use the plugin for woocommerce - Extra Product Options & Add-Ons for WooCommerce by ThemeComplete. And I have these images used in the extra product options. They are blurry. When you have dropdowns, or the extra product options, there's a feature where you can replace the single product image with a new image thats based on the product option someone selected from the dropdown. Well the initial image is fine, but after you use the dropdown the following image is very blury.
I've tried replacing my image with higher resolution I've tried changing the media settings for images to have higher resolution I've tried changing the woocommerce product image settings
Heres a link for an example: https://www.itguyscustompcbuilds.com/?product=base-gamer-pre-built-rig
