You can have an AutoViewer gallery point towards a specific XML file by using the xmlURL option in your gallery's embedding code, such as:
<script type="text/javascript" src="swfobject.js"></script>
<div id="flashcontent">AutoViewer requires JavaScript and the Flash Player.
<a href="http://www.macromedia.com/go/getflashplayer/">Get Flash.</a></div>
<script type="text/javascript">
var fo = new SWFObject("autoviewer.swf", "viewer", "800", "600", "8", "#181818");
fo.addVariable("xmlURL", "gallerydata.xml");
fo.write("flashcontent");
</script>
If you continue to experience difficulties, please post the URL to your gallery so that I can take a look.
