On the shop's main page, I'd like to use a bigger image for my featured products than the image that is used for the other products. I know this image size is determined by my settings in WooCommerce>Settings>Catalog>Image Options>Catalog Images, but I don't want to increase the image size there and have to control the image size for the normal products with CSS. This would mean using bigger files than I need for most of the site.
Is there either a file where I can change which image size featured products calls, or a filter I can use to achieve this?
Any and all help very much appreciated!
