Photo fade in/out

hello all

I have this piece of code that loops through a set of photo’s but now I want it to be able to fade in and out while looping. I have pretty much no knowledge of actionscripting so I was hoping someone could help me out here.

Here’s the code:

//Set amount of time to hold each image onscreen 
var inSeconds:Number = 7; 
var xmlBanners:XML = new XML(); 

xmlBanners.ignoreWhite = true; 
xmlBanners.onLoad = function(success) {     
	if (success) {
		parseXML(xmlBanners);
	} 
}; 
xmlBanners.load("_lib/file.xml"); 
function parseXML(banners_XML) {
	var bannerNum:Number = 0;  
	var xnRoot:XMLNode = banners_XML.firstChild;
	var xnBanner:XMLNode;
	
	xnBanner = xnRoot.childNodes[bannerNum];
	myFile = xnBanner.firstChild.firstChild;
	myURL = xnBanner.lastChild.firstChild;
	
	this.onEnterFrame = function() {
		//This creates the first clip without delay
		this.createEmptyMovieClip("my_mc", this.getNextHighestDepth());
		var movLoad:MovieClipLoader = new MovieClipLoader();
		var myListener:Object = new Object();
		myListener.onLoadInit = function(thisMc:MovieClip) {
			thisMc.onRelease = function() {
				getURL(myURL);
			};
		};
		movLoad.addListener(myListener);
		movLoad.loadClip("_lib/photos/"+myFile, this.my_mc);
		delete this.onEnterFrame;
	};
	//After that, they are on a timed change
	this.getNewPic = function() {
		var maxBanners:Number = xnRoot.childNodes.length;
		if (bannerNum == maxBanners-1) {
			bannerNum = 0;
		}
		else {
			bannerNum++;
		}
		xnBanner = xnRoot.childNodes[bannerNum];
		myFile = xnBanner.firstChild.firstChild;
		myURL = xnBanner.lastChild.firstChild;
		//
		this.createEmptyMovieClip("my_mc", this.getNextHighestDepth());
		var movLoad:MovieClipLoader = new MovieClipLoader();
		var myListener:Object = new Object();
		myListener.onLoadInit = function(thisMc:MovieClip) {
			thisMc.onRelease = function() {
				getURL(myURL);
			};
		};
		movLoad.addListener(myListener);
		movLoad.loadClip("_lib/photos/"+myFile, this.my_mc);
	};
	var myInt = setInterval(this, "getNewPic", (inSeconds*1000));
}
