Hello Leo.
Currently only the main image width is able to be set in the customiser.
I’d like to hard-crop the main image square (not the thumbnails).
I believe this would be a good feature/option to have in generate press as it would maintain consistency throughout product pages. It would also look a hell of a lot better on mobile devices.
Woocommerce did in fact use to have height and width adjustments for main product images in the past but removed this functionality.
Would appreciate if you could pass my comments onto the development team for review and potentially provide a work-around in the meantime.
Regards,
Pau
