title: Animated gif no longer animated on jquery .show()
body: <p>As far as I can tell this only affects IE 8.</p>
  
  <p>Using the following code, the gif appears but is not animated (stuck in one position):</p>
  
  <pre><code>$("#&lt;%=assessmentListLinkClientID() %&gt;").click(function(){
          $("#assessmentListLoaderImg").show();
      });
  </code></pre>
  
  <p>I've also used <code>.css('display', 'block')</code> with the same results.</p>
  
  <p>Is there an accepted way (perhaps better than this) that produces reliable cross-browser results for showing an animated gif?</p>
