<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/thickbox.js"></script>

you need to edit this code to match your upload folder. In general you will use the clientscript folder for the Javascript-Uploads. So change the loaction in the code to:

<script type="text/javascript" src="clientscript/jquery.js"></script>
<script type="text/javascript" src="clientscript/thickbox.js"></script>

Maybe you have to upload all files to your special style folders too when using different styles and change the code to match your settings.

The thickbox.css should be uploaded to forum root!
