Load images from XML to specific movieclip

Question

I'm still begginer. I have to load images in specific movieclip, because they're loading over all the other layers. What should I do?
I made a simple slideshow by tutorial.
I guess it would be better that I show all the code not specific parts:
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
var my_speed:Number;
var my_total:Number;
var my_images:XMLList;
var my_loaders_array:Array=[];
var my_labels_array:Array=[];
var my_success_counter:Number=0;
var my_playback_counter:Number=0;
var my_slideshow:Sprite = new Sprite();
var my_image_slides:Sprite = new Sprite();
var my_label_slides:Sprite = new Sprite();
var my_preloader:TextField;
var my_timer:Timer;
var my_prev_tween:Tween;
var my_tweens_array:Array=[];
var my_xml_loader:URLLoader = new URLLoader();
my_xml_loader.load(new URLRequest("sshow.xml"));
my_xml_loader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void {
    var my_xml:XML=new XML(e.target.data);
    my_speed=my_xml.@SPEED;
    my_images=my_xml.IMAGE;
    my_total=my_images.length();
    loadImages();
    my_xml_loader.removeEventListener(Event.COMPLETE, processXML);
    my_xml_loader=null;
function loadImages():void {
    for (var i:Number = 0; i < my_total; i++) {
        var my_url:String=my_images[i].@URL;
        var my_loader:Loader = new Loader();
        my_loader.load(new URLRequest(my_url));
        my_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
        my_loaders_array.push(my_loader);
    my_preloader = new TextField();
    my_preloader.text="Loading";
    my_preloader.autoSize=TextFieldAutoSize.CENTER;
    my_preloader.x = (stage.stageWidth - my_preloader.width)/2;
    my_preloader.y = (stage.stageHeight - my_preloader.height)/2;
    addChild(my_preloader);
function onComplete(e:Event):void {
    my_success_counter++;
    if (my_success_counter==my_total) {
        startShow();
    var my_loaderInfo:LoaderInfo=LoaderInfo(e.target);
    my_loaderInfo.removeEventListener(Event.COMPLETE, onComplete);
function startShow():void {
    removeChild(my_preloader);
    my_preloader=null;
    addChild(my_slideshow);
    my_slideshow.addChild(my_image_slides);
    nextImage();
    my_timer=new Timer(my_speed*1000);
    my_timer.addEventListener(TimerEvent.TIMER, timerListener);
    my_timer.start();
function nextImage():void {
    var my_image:Loader=Loader(my_loaders_array[my_playback_counter]);
    my_image_slides.addChild(my_image);
    my_image.x = (stage.stageWidth - my_image.width)/2;
    my_image.y = (stage.stageHeight - my_image.height-20)/2;
    my_tweens_array[0]=new Tween(my_image,"alpha",Strong.easeOut,0,1,2,true);
function timerListener(e:TimerEvent):void {
    hidePrev();
    my_playback_counter++;
    if (my_playback_counter==my_total) {
        my_playback_counter=0;
    nextImage();
function hidePrev():void {
    var my_image:Loader=Loader(my_image_slides.getChildAt(0));
    my_prev_tween=new Tween(my_image,"alpha",Strong.easeOut,1,0,2,true);
    my_prev_tween.addEventListener(TweenEvent.MOTION_FINISH, onFadeOut);
function onFadeOut(e:TweenEvent):void {
    my_image_slides.removeChildAt(0);

I don't see a problem in the code you provided. All the pictures are put in single one MovieClip, my_image_slides. Of course, there can be only one DisplayObject in a DisplayObjectContainer's layer (depth), so when you call function addChild again and again, the child displayObjects keep stacking up one on the other. I found one strange thing though:
my_tweens_array[0]=new Tween(my_image,"alpha",Strong.easeOut,0,1,2,true);
Why would you create an array just to limit it to one item and overwrite it every time? I would use this instead:
my_tweens_array.push(new Tween(my_image,"alpha",Strong.easeOut,0,1,2,true));
Can you upload it somwhere so we can see it in action? At this point I can only guess what the problem is.
