The browser would need to be able to find the required files to run the slideshow; One line in the page code:
<script type="text/javascript" src="file:///Pray4EpicShores/clients_00/lostislandofbaru/videomediaslideshow.js"></script>
Make sure that all paths to the required files are correct (and that links and includes are relative to document, not site root when added in Dreamweaver)
