Loads images http on https (SSL) pages

I’m using this on a site that runs WooCommerce. On SSL secured pages (https) it loads the images over http, which causes warnings in many browsers. Any chance this can be updated to just load a relative path, like /wp-content/uploads/2014/08/image.jpg instead of including the full URL, with http:// ? Or perhaps some other solution. But either way, it’d be very nice if it could play nicely with sites that have SSL on some pages, and not others.
