Lazy loading for bootstrap's carousel

lazy-carousel.js

//not a perfect lazy load as it occurs on the slide event, not prior to the slide itself
$(function() {
  return $("#carousel").on("slide.bs.carousel", function(event) {
    var lazy;
    lazy = $(event.relatedTarget).find("img[data-src]");
    lazy.attr("src", lazy.data("src"));
    lazy.removeAttr("data-src");
  });
});
