I am getting an "F" on gtmetrix for serving scaled images. I want the product image to be 500X638 on the product page but they are being served at 215X275 on the shop page's "recent products" box.
/wp-content/uploads/2014/01/test.png is resized in HTML or CSS from 500x638 to 215x275. Serving a scaled image could save 199.0KiB (81% reduction).
I can reduce the size of the images to 215X275 but I want the image to stay large on product page and small on the shop page.
Is there a way to easily fix this?
