Jcarousel how to set start point

I am currenty using Jcarousel with a light box plugin. I have some thumbnails and when each one is clicked a light box pops up with the larger version of thumbnail in it, also i have in that light box the ability to click left or right to rotate throught the other thumbnails(this is all generated using the Jcarousel) My issue is i would like the carousel to start the corresponding thumb nail that was clicked to open the light box:

HTML:

<div id="productAlts">
    <div class="altWrap">
        <a id="close_x" class="close" href="#" title="close quick view" ></a>
        <ul>
        <% int altImageCount = 0;
           foreach (var img in addtImages)
           {
               altImageCount++;
           }
        %>
        <% int i = 0;
           foreach (var img in addtImages)
           {
               i++;
               if (i != altImageCount)
               {%>
                  <li class="<%=img %>">
                  <img src="http://www.someurl.com/images/products/<%=img.Replace(".jpg", "") %>l.jpg"  alt="<%= Model.Name %>" title="<%= Model.Name %>" width="500" height="500" />
                  </li>
              <% }
           } %>
       </ul>
   </div>

jquery:

    function QuickAlternate() {
$('.alternateImages ul li').click(f开发者_开发问答unction (e) {
    $('#productAlts').lightbox_me({
        centered: true,
        onLoad: function () {
$('#productAlts ul').jcarousel({
    wrap: 'circular', scroll: 1, visible: 1
});
        }
    });
    e.preventDefault();
});

}

If anyone can help it would be very appreciated since i have been banging my head against this for a while

Not entirely sure I understand what you're looking for, but it sounds like the start option as shown in http://sorgalla.com/projects/jcarousel/#Configuration should do what you want? So something like this:

$('#productAlts ul').jcarousel({
    wrap: 'circular', scroll: 1, visible: 1, start: 4
});

would start on the 4th one?
