title: Meteor: Preloading of image(s)
body: <p>I built a meteor app with a big background image. Right now the app starts and the user can watch while the image is loading. It would be better for me to load the needed background-image first and if the loading has finished the app will show up. I tried to search for some concepts for that, but I didn't find a solution, which is usable with meteor.</p>
  
  <p>So I thought of using the waitOn-function of the Iron-Router:</p>
  
  <pre><code>Router.route('/', {
      name: 'home',
      yieldRegions: {
          'navigationBar': { to: 'navigation' },
          'contentPage':   { to: 'content' } 
      },
      waitOn: function() { 
           // Loading image, and if loaded, go further on...
      }
  });
  </code></pre>
  
  <p>Maybe someone has a idea how to do that...</p>
