for loop works for all but onRelease

[mlecho]

i am making a basic picture viewer....and trying to better understand for loops. i have the 7 thumbnails programatically generated and positioned. The onRollOver, and onRollOut effects work fine for each. The only thing i am not understanding is how to make each thumbnail upon onRelease unique...in other words, i have to write the onRelease functions seperately for each thumbnail in order to bring a new large picture to the stage....is there a way to do this within the "for" loop- or at least more dynamically?:

function loadImages(myXML) {
	var mcImage:MovieClip;
	// Load the four images.
	for (var i = 0; i<=7; i++) {
		frames[i]._visible=false
		
		
		mcImage = this.createEmptyMovieClip("mcImage"+i, this.getNextHighestDepth());
		mcImage.createEmptyMovieClip("mcHolder", mcImage.getNextHighestDepth());
		
		mcImage._alpha = 30;
		mcImage.onRollOver = function() {
			upAlpha(this);
		};
		mcImage.onRollOut = function() {
			downAlpha(this);
		};
		mcImage0.onPress = function() {
			loadBigImage(0);
		};
		mcImage1.onPress = function() {
			loadBigImage(1)
		};
		mcImage2.onPress = function() {
			loadBigImage(2)
		};
		mcImage3.onPress = function() {
			loadBigImage(3)
		};
		mcImage4.onPress = function() {
			loadBigImage(4)
			
		};
		mcImage5.onPress = function() {
			loadBigImage(5)
			
		};
		mcImage6.onPress = function() {
			loadBigImage(6)
			
		};
		mcImage7.onPress = function() {
			loadBigImage(7)
			
		};
		
		var mclLoader:MovieClipLoader = new MovieClipLoader();
		var mclListener:Object = new Object();
		var mclLoader:MovieClipLoader = new MovieClipLoader();
		mclLoader.addListener(mclListener);
		//this listerner will always refrence the clip immediately loaded
		mclListener.onLoadInit = function(mcClip:MovieClip) {
			if(nX==undefined){
				nX=Stage.width/2-(mcClip._width +200);
				nY=20;
			}
			mcClip._parent._x=nX;
			mcClip._parent._y=nY;
			nX+= mcClip._width+10;
			if (mcClip._x>Stage.width){
				//define method to start second row
			}
		};
		mclLoader.addListener(mclListener);
		mclLoader.loadClip("images/"+myXML.firstChild.childNodes[i].attributes.thumb,mcImage.mcHolder);
	}
}
function loadBigImage(index) {
	var bigImageX:Number;
	var bigImageY:Number;
	var bigImageLoader:MovieClipLoader= new MovieClipLoader;
	var bigImageListener:Object= new Object
	bigImageListener.onLoadInit=function (mcCurrentBigImage:MovieClip):Void{
		mcCurrentBigImage._alpha=80;
		
		/*if(bigImageX==undefined){
			bigImageX= Stage.width/2- (mcCurrentBigImage._width)/2
			bigImageY= Stage.height/4-50;
		}
		mcCurrentBigImage._x=bigImageX;
		mcCurrentBigImage._y=bigImageY;*/

	bigImageLoader.loadClip("images/"+myXML.firstChild.childNodes[index].attributes.picture, imageTank);
	bigImageLoader.addListener(bigImageListener);

var myXML:XML = new XML();
myXML.ignoreWhite = true;
