// $('#content-with-images').imagesLoaded( myFunction )
// execute a callback when all images inside a parent have loaded.
// needed because .load() doesn't work on cached images

// Useful for Masonry or Isotope, triggering dynamic layout
// after images have loaded:
// $('#content').imagesLoaded( function(){
// $('#content').masonry();
// });

// callback function is passed the last image to load
// as an argument, and the collection as `this`
