jcarousel, index of current thumbnail or item?

jcarousel, index of current thumbnail or item?

jcarousel is working but with over 40 thumbnails how do I keep the active thumbnail in the carousel? I don't know what this might be called or what to search for? Is it itemLoadCallback?  index of current item? something else?

Here is the page, vertical scroller on right, when you click on a thumbnail the carousel goes back to 1st thumbnail but I prefer it to stay on thumbnail clicked.


here is the jCarousel configuration page, is one of these properties going to work for me and how to implement it?   http://sorgalla.com/projects/jcarousel/#Configuration

here is script on page to make jcarousel work

<script type="text/javascript">

jQuery(document).ready(function() {
        vertical: true,
        scroll: 3
