Fixes the failed $.get() calls but still do we need to invoke it via setInterval ?

  $('.cards .img img').each(function(index, element) {
    document.preloads.push($(element).data('hover'));

  });

@owocki Can't we just directly do $.get here instead ?
Haven't changed this cause I wanna check why this was written this way (so that I don't break anything unknowingly )

@kziemianek completed the original bounty for this. Any thoughts?

@thelostone-mc @mbeacom I am removing the $.get code for the time. Hope you both are okay with it?
