Flash slideshow with fade transition

Hi, I’ve created a slideshow that contains 137 images using this code.
////////////////////////////
var imageNumber:Number=1;
var starTimer:Timer=new Timer(3000,10000);
starTimer.addEventListener(TimerEvent.TIMER,nextImage);

function nextImage(event:TimerEvent):void {
//Adding to the current value +1
imageNumber++;
largeImageLoader.source=+ imageNumber+".jpg";
}

starTimer.start();
////////////////////////////

However the problem is I want it to fade from 1 image to the next

I tried using tween lite to tween the alpha of the images to 0 so it would slowly load the next image in but since they’re loaded in from the same loader you don’t see it fading from one image to another, just fading to white…
