title: page loading and priority
body: <p>I have a page with a lot of galleries (using galleria plus fancybox ) and an image slider on top (nivo slider). 
  The problem is that the slider take time to load, cause the browser is loading the galleries meanwhile. 
  Now i would like to give the slider a priority ,so the page would have at least it's structure built,  or maybe, let the galleries load only on click. </p>
  
  <pre><code>&lt;script type="text/javascript"&gt;&lt;!--fancybox--&gt;
      $(document).ready(function() {
          $(".fancybox").fancybox();
      });
  &lt;/script&gt;
  
  &lt;script type='text/javascript'&gt;
              Galleria.loadTheme('galleria/themes/classic/galleria.classic.min.js');
              Galleria.run('#gallery-1,#gallery-2,#gallery-3,#gallery-4,#gallery-5,#gallery-6,#gallery-7,#gallery-8,#gallery-9,#gallery-10,#gallery-11,#gallery-12,#gallery-1b,#gallery-2b,#gallery-3b,#gallery-4b');
   &lt;/script&gt;
  </code></pre>
