How to change product image sizes in ShopIsle
You might want to change the image sizes in Shopisle theme because they are either bigger than what you want or your images are cut off (cropped).
To fix this issue please go to Appearance -> Customize -> Woocommerce -> Product Images section.
Here you can set the Main image width, Thumbnail width, and Thumbnail cropping. There is no option for adding the height because WooCommerce calculate it automatically according to your settings.
As soon as you make any changes and hit publish button, WooCommerce will automatically generate the new image sizes.
If you can't see the changes on your website, make sure you have cleared the browser cache.
