How do I call on a specific child in a container

Question

I am loaded images into a container that is being displayed on a map.  I've created a string of my images names and am looping a loader to load each image and add them to the container.
var overlays=["compsmall.png","compsmall3.png","compsmall3.png","compsmall4.png"]
var overlay_container:MovieClip= new MovieClip();
function calloverlays():void
for (var i:Number = 0; i < overlays.length; i++)
var overlay_url = overlays[i];
var overlay_loader = new Loader();
overlay_loader.load(new URLRequest(overlay_url));
overlay_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, overlayLoaded);
function overlayLoaded(e:Event):void
var my_overlay:Loader = Loader(e.target.loader);
overlay_container.addChild(my_overlay);
Once all of my images are loaded into the container overaly_container how can I call on a specific child of the container?  For example how can I call on compsmall2.png once its been loaded into overlay_container?
I place these images onto a map by placing the whole container at the correct location.  I then turn layers on/off by adding and removing the children within the container.  This is why I'd like to specify a specific object in the parent.
Thanks in advance,

Well, there are better ways given how you're loading - nesting functions is generally frowned upon... but this should get you started anyway. This is a little function that you could use to hide one of your loaded images:
function hideLayer(image:String){
    var c:int = overlay_container.numChildren;
    for(var i:int = 0; i < c; i++){
        if(Loader(overlay_container.getChildAt(i)).contentLoaderInfo.url.indexOf(image) != -1){
            overlay_container.getChildAt(i).visible = false;
            break;
and then use like: hideLayer("compsmall2.png");
But like I said, there are better ways. But you'd need to restructure your code - get rid of the nested functions, and the loop... then load each image one at a time. Then you know the index in the array of the image being loaded and can match that with the index inside the container...
