I’ll add to this question to re-open it:
Why the heck do ALL eCommerce sites presume product images are going to be square.
I need to display full width landscape product images on my single product pages.
So, without resorting to zooming, how can I alter the single product page to allow for landscape product images.
Alternatively, how can I display the entire add to cart summary section (with quantity, variation selections, add-ons, etc) as a short code without including the product images.
