I understand that you are experiencing issues with blurry images on your site, is this correct?
Anytime a new theme is activated or image dimension settings are changed, old thumbnails need to be regenerated under WooCommerce → Status → Tools → Regenerate Thumbnails.
We recommend a minimum size of 800 x 800 pixels, width and height. This renders well for the main/featured image, catalog image and thumbnail image. Images that are larger are even better, especially if you’re selling items with great detail.
Also, the general rule of thumb is that your image dimensions should match or be higher than those of your theme.
Please can you work through the below support guide and see if any of the suggestions provided there help resolve the issue you are facing:

As for your screenshot and image, I took the header down so I could have a professional-looking site. I added a logo in the Site Identity area of the Customize panel. I formatted it with CSS instead so I could have a functional, professional site while awaiting an answer. I just need to know how to use the header function without my headers looking like I took my glasses off. This is where I changed from the header to the logo.
