title: jqZoom change image source
body: <p>I have a gallery of 5 thumbnails and one larger image. I have jqZoom tied to the large image so when you mouse over it, you can see a zoomed in version. 
  I'm having trouble when a user clicks an alternate thumbnail. I can get the larger image to change, but the zoomed in image remains the original image. I can't make jqZoom change the zoomed in image to match the thumbnail. 
  Here is an example of what I'm trying to do. You click on the text and the thumbnail changes, but the larger jqZoom image remains the same. How do I change this so that jqZoom loads the new image in the zoom area?</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  
  $(function() {
   var options = {
   zoomWidth: 250,
   zoomHeight: 250,
   showEffect: 'fadein',
   hideEffect: 'fadeout',
   fadeinSpeed: 'fast',
   fadeoutSpeed: 'fast',
   showPreload: true,
   title: false,
   xOffset: 100
   };
   $(".jqzoom").jqzoom(options); 
  
  });
  
  function changeImgSrc() {
   document.getElementById('bigImage').src = '4.jpg';
   document.getElementById('smallImage').src = '3.jpg';
    var options = {
   zoomWidth: 400,
   zoomHeight: 400,
   showEffect: 'fadein',
   hideEffect: 'fadeout',
   fadeinSpeed: 'fast',
   fadeoutSpeed: 'fast',
   showPreload: true,
   title: false,
   xOffset: 100,
   containerImgSmall: '3.jpg',
   containerImgLarge: '4.jpg'
   };
   $(".jqzoom").jqzoom(options);
  
  }
  &lt;/script&gt;
  &lt;/head&gt;
  
  &lt;body&gt;
  &lt;div id="content" style="margin-top:100px;margin-left:100px;"&gt;
  &lt;a id="bigImage" href="2.jpg" class="jqzoom" style="" title="Product Zoom"&gt;
    &lt;img id="smallImage" src="1.jpg" title="Product Zoom" style="border: 0px none;"&gt;
  &lt;/a&gt;&lt;/select&gt;
  &lt;br&gt;
  &lt;div id="img" onClick="document.getElementById('bigImage').src = '4.jpg';changeImgSrc();"&gt;click here to change source&lt;/div&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>Thanks for your help!!</p>
