Hi Geoffrey,

Looking at the date of your post, I guess you will have solved the problem by now. For the record however, I got it working like this.

First I added the shadowbox scripts to my skin folder in a subdirectory called js/shadowbox. Then I added the shadowbox script references and initialisation at the top of the skin .ascx file for that page that was to use shadowbox, like this:

<link rel="stylesheet" type="text/css" href="<%=skinpath%>/js/shadowbox/shadowbox.css">
<script type="text/javascript" src="<%=skinpath%>/js/shadowbox/shadowbox.js"></script>
<script type="text/javascript">
Shadowbox.init({
    handleOversize: "drag",
    modal: true
});
</script>

Finally I added a rel="shadowbox" to the link to the content I wanted to display. When I loaded the page and clicked the link, the relevant content was loaded in a modal lightbox, the way I wanted it to.
