Movieclip Class

Hello!
I have AS in main timeline:


for (var i:Number = 0; i < 10; i++) {
    var pic_mc:thumb=new thumb();
    pic_mc.name = "pic"+i;
    stage_holder.addChild(pic_mc);
    pic_mc.loadPic(pic_url);

creates movieclips like this:
stage_holder.pic0
stage_holder.pic1 etc.

Inside movieclip “thumb” I have movieClip named “b”, there I want to add loaded picture, but don’t know how to do it! Also I want to trace movieclip’s name “pic1”, "pic2"etc.

movieClip thumb has class:

package 
{
 import fl.transitions.*;
 import flash.display.*;
 import flash.events.*;
 import flash.net.URLRequest;

 import flash.display.Loader 

public class thumb extends MovieClip
    {
        private var myLoader:Loader;
       public function thumb()
        {
         **    //doesn't show movieclip name! **
            trace("created "+ name);
        }
        
 public function loadPic(links:String)
        {
var myLoader:Loader = new Loader();

myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderReady);

var fileRequest:URLRequest = new URLRequest(links);
myLoader.load(fileRequest);

        }
        
        

public function onLoaderReady(e:Event) {     

**  //here I want to add picture to movieclip: stage_holder.pic1.b   **
b.addChild(myLoader);
   
}  }

}
