How to hide images before layout

[speg]

How do you hide the images before Masonry organizes them into a grid? My shows the images in a pile as they are being loaded and then finally once they are all loaded then Masonry organizes them nicely.

they use imagesLoaded

$container.imagesLoaded(function(){
      $container.masonry({
        itemSelector: 'li.post'
      });
    });
