XML Gallery and Slideshow Help

First off let me say that this forum is a lifesaver. I managed to figure out the links in xml file myself, but I cant seem to get the next/previous buttons working the way I want them to.

I have got them to work to the point where they will bring up the next image, this is until it gets to the end of the xml node, then it wont start over from the beginning if I hit next.

Can someone help me -

Here is my code:

//-----------------------
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
url = [];
delay = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue; 
url* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
delay* = xmlNode.childNodes*.childNodes[3].firstChild.nodeValue;



}


firstImage();
} else {
content = "file not loaded!";
}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
