I understand that the main recipe image is resized, that the full-size image uses the 'Large size' and the in-recipe image uses the 'Medium size' that are set in the Settings > Media portion of WordPress.
Is it possible to use custom image sizes for the main image (i.e. creating the new dimensions in functions.php)?
Is this a feature that's already in the premium version of the plugin? I'm using the free version, at the moment.
