XML Gallery: Change from MouseEvent to automatic?

Question

I am trying to edit an old XML gallery that I made so that it will scroll through the images automatically, without any user interaction at all. Currently it's set to scroll through them one at a time and is controlled by mouse clicks. I can't figure out how to change it. Any help would be greatly appreciated!!
Here's my code:
var xmlRequest:URLRequest = new URLRequest("homeImages.xml");
var xmlLoader:URLLoader = new URLLoader(xmlRequest);
var imgData:XML;
var imageLoader:Loader;
var rawImage:String;
var rawH:String;
var rawW:String;
var imgNum:Number = 0;
var checkSec:Timer = new Timer(100);
var numberOfChildren:Number;
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
Images_mc.addEventListener(MouseEvent.CLICK, nextImgF);
Images_mc.buttonMode = true;
function xmlLoaded(event:Event):void
checkSec.start();
checkSec.addEventListener(TimerEvent.TIMER, checkerF);
imgData = new XML(event.target.data);
function packagedF():void
checkSec.removeEventListener(TimerEvent.TIMER, checkerF);
rawImage = imgData.image[imgNum].imgURL;
numberOfChildren = imgData.*.length();
rawW = imgData.image[imgNum].imgW;
rawH = imgData.image[imgNum].imgH;
imageLoader = new Loader;
imageLoader.load(new URLRequest(rawImage));
Images_mc.addChild(imageLoader);
imageLoader.x = (Images_mc.width - Number(rawW)) /2;
imageLoader.y = (Images_mc.height - Number(rawH)) /2;
function checkerF(event:TimerEvent):void
if(imgNum == 0)
  packagedF();
else if(imgNum < numberOfChildren)
  imageLoader.unload();
  packagedF();
else
  imageLoader.unload();
  imgNum = 0;
  packagedF();
function nextImgF(event:MouseEvent):void
checkSec.addEventListener(TimerEvent.TIMER, checkerF);
imgNum++;

You should be able to incorporate a second Timer object that you use for the automatic advancing....
var autoTimer:Timer = new Timer(2000); // adjust for desired msec
autoTimer.addEventListener(TimerEvent.TIMER, nextImgF);
Since you are loading images with each call to that function, you may end up needing to incorporate more control of the timer and not have it firing repeatedly on its own, which means adding a listener for loading completion, putting a limit on the number of repeats to once, and assign a new Timer each time thru... var autoTimer:Timer;  .... autoTimer = new Timer(2000, 1);....
