Hello,
I saw the screenshot you attached.
1) Please provide the URL of the website to check it myself and help you out accordingly.
2) Basically the product and categories images are controlled by woocommerce and our theme doesn’t influence this. WooCommerce Allows some settings that you can find under Appearance >> Customize >> WooCommerce >> Product Images.
You can also read our detailed documentation for further help:

The settings work the same for products and categories.
Regards.
