title: Isotope not working with imagesLoaded?
body: <p>I'm using jQuery Isotope to create a horizontal layout, aligning DIVs with 100% height next to each other and center images inside each DIV vertically. So for, I'm calling Isotope like this and everything works fine in Chrome (locally):</p>
  
  <pre><code>$(function(){
      var $container = $('#container');
      $container.isotope({
          itemSelector : '.itemwrap',
          layoutMode: 'horizontal',
          horizontal: {
              verticalAlignment: 0.5
          }
      });
  });
  </code></pre>
  
  <p>As the images take time to load, they tend to mess up the Isotope layout, so I'm trying to work with the imagesLoaded fix:
  <a href="http://isotope.metafizzy.co/appendix.html" rel="noreferrer">http://isotope.metafizzy.co/appendix.html</a></p>
  
  <p>I implemented this fix like this:</p>
  
  <pre><code>$(function(){
      var $container = $('#container');
      $container.imagesLoaded( function(){
          $container.isotope({
              itemSelector : '.itemwrap',
              layoutMode: 'horizontal',
              horizontal: {
                  verticalAlignment: 0.5
              }
          });
      });
  });
  </code></pre>
  
  <p>With this imagesLoaded, the Isotope does not load at all anymore. Removing imagesLoaded, Isotope kicks in again (but with the messed up layouts). Does anyone know, where the mistake lies?</p>
  
  <p>Thanks!</p>
