Please Help me

Hello,
I have been using this code
import com.greensock.*;

const COLUMNS:uint=8;
const ROWS:uint=4;
 
var imagesGrid : Array = new Array();   
 
var imageLoader:Loader = new Loader();
imageLoader.load(new URLRequest("corissonintro.jpg"));
imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onImageLoaded);
 
function onImageLoaded(e:Event):void {
 
   var originalBitmapData:BitmapData = e.target.content.bitmapData;
 
   var imageWidth : Number  = originalBitmapData.width / COLUMNS;
    var imageHeight : Number = originalBitmapData.height / ROWS;

   for (var i = 0; i < COLUMNS; i++) {
 
      for (var j = 0; j < ROWS; j++) {
 
         var imageHolder:MovieClip = new MovieClip();

         var image:Bitmap = new Bitmap();
         image.bitmapData=new BitmapData(imageWidth,imageHeight);
         image.bitmapData.copyPixels(
                        originalBitmapData,
                        new Rectangle(i * imageWidth, j * imageHeight,imageWidth, imageHeight),
                        new Point(0,0));
 
         image.smoothing = true;
              imageHolder.addChild(image);
 
         image.y = -imageHeight / 2;
 
         imageHolder.x= i*imageWidth + imageWidth/2;
         imageHolder.y= j*imageHeight + imageHeight/2;
 
         imageHolder.alpha=0;
         imageHolder.delaytime = Math.random();
 
         imagesGrid.push(imageHolder);
         addChild(imageHolder);
 
      }
   }
   revealImage();
}
 
function revealImage():void {
   for (var i:int = 0; i < imagesGrid.length; i++){
      var imageGrid:MovieClip = imagesGrid* as MovieClip;
      TweenLite.to(imageGrid,.5,{rotationY: -360,alpha:1,delay:imageGrid.delaytime});
   }
}

stop();

To insert an image effect into my flash. The problem is i have no idea how to get rid of it on the next frames. It simply appears in every frame i try to create in flash.
Please help me keep it only on one frame.
Thank you very much!
