title: Load a "Loading" image for galley first
body: <p>Is it possible to load a animated loading gif. It needs to load before the images in the gallery or there is no use having it?</p>
  
  <p>The image will be loaded as a background image via css</p>
  
  <pre><code>&lt;link rel="stylesheet" href="loading.gif" /&gt;
  </code></pre>
  
  <p>Thanks in advance</p>
