Disable for small screens

I would like to disable Magnific Popup for screens smaller than a certain dimension so that mobile users will be linked to the actual file and be able to properly zoom-in on large images.

Any suggestions on how this might be possible? I found this post on Stackoverflow and someone posted this code:

https://stackoverflow.com/questions/12832831/lightbox-not-playing-nice-with-mobile-device

$(document).ready(function() {
    // initialize the lightbox
    $('.fancybox').fancybox({
        beforeLoad: function() {
            var windowsize = $(window).width();
            // test the viewport size to see if it's smaller than 480px
            if (windowsize < 480) {
                // cancel the lightbox and load the link url
                $.fancybox.cancel();
            }
        }
    });
});

Not sure if it’s possible to implement that code with this plugin.
