Adding timing to Gallery

I am trying to add a time feature to the gallery here on Kirupa. There will be next and back buttons to change data from xml, however I would like to add a time feature to change every 5 - 8 seconds. This is how I am going about it should I be using setInt it is talked about in many other tutorials as listed for tim?:


function loadXML(loaded) { 
if (loaded) { 
xmlNode = this.firstChild; 
image = []; 
title = [];
button = [];
description = [];
link = [];
total = xmlNode.childNodes.length; 
for (i=0; i<total; i++) { 
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue; 
title* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
button* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[3].firstChild.nodeValue; 
link* = xmlNode.childNodes*.childNodes[4].firstChild.nodeValue;
} 
firstImage(); 
} else { 
content = "file not loaded!"; 
} 
} 
xmlData = new XML(); 
xmlData.ignoreWhite = true; 
xmlData.onLoad = loadXML; 
xmlData.load("stuff.xml");

function picture_num() {

picture.loadMovie(image[p], 1);

Cause I would like to have next back and pause as well pausing playing state. Hit me with any tut or reading on here if anyone can recommend.
