Why my dynamic movieclip change size

1

I have a rectangle shaped movieclip that is my contentPlaceHolder for my content. I added action script to dynamically load pictures. I addChild() the loaded pictures to my contenplaceholder movie clip. The problem is when i export and play the movie pictures are loaded but not in there actual size.

the code:
var xmlLoaders:URLLoader = new URLLoader();
var xmlDatas:XML = new XML();

xmlLoaders.addEventListener(Event.COMPLETE, LoadXMLs);
xmlLoaders.load(new URLRequest(“content/diskografija.xml”));

function LoadXMLs(e:Event):void{
var xmlData = new XML(e.target.data);
var albums:XMLList=xmlData.albums.children();
for(var i:int=0;i<albums.length();++i){
var album:XMLList=albums*.attributes();
var r:URLRequest=new URLRequest(album[1].toString());
var loader:Loader=new Loader();
var clip:MovieClip=new MovieClip();

loader.load(r);
clip.addChild(loader);
addChild(clip);
	clip.y=10+150*i;
clip.x=10;

}
}

Pictures are shown in the right order with my clip.y code but they are not their actual size.
