Reply To: quality of images

Hello,

Try to disable cropping and upload images of equal size. Please do not edit theme templates code. Your site is not in English seems that you are trying to set images for posts, not for products (ajustes.png) the Default WooCommerce does not have the option to configure image size. Our theme does Appearance > Customize > WooCommerce > Product images > disable Cropping.

Best Regards
