Hello,
1. Basically the product images and categories images are controlled by woocommerce and our theme doesn’t influence this.
Woocommerce provides settings for images that you can find under Appearance >> Customise >> WooCommerce >> Product Images.
you can read our detailed documentation about image alignment and content in the following link:

2. By default the Shop page is not editable using the page builders.
Best Regards
