So I've been banging my head against the wall lately trying to adjust my Product Image quality. My shop design needed a higher resolution for the image main page since I was doing a large grid but my product images kept coming out low quality. I tried overriding it via CSS, I tried looking in WooCommerce plugin settings, re-uploading higher quality images, and tried so many things in my DIVI theme but nothing worked. I accidentally fell upon the settings for it in the long forgotten theme customizer.

Simple, I know. I'm hoping I'm not the only one that this much difficulty figuring it out. So I decided making a post about it and hopefully that could help. Very little adjustments for WooCommerce are actually made in the theme customizer so I just would've never thought to look there.

TLDR: It's in Theme Customizer > WooCommerce > Product Images
