Adding border to movie clips

Hi all,

I have a scrolling image strip that loads images from xml. I was wondering how I could attach a border to the movie clips that the images are loaded into. I know how to use the drawing API, but I can’t seem to attach a border to each movie clip. I’m posting the code below. Any help would be greatly appreciated. Thanks.

 
cliparray = [];
function loadXML(loaded) {
 if (loaded) {
  xmlNode = this.firstChild;
  thumbnails = [];
  total = xmlNode.childNodes.length;
  for (i=0; i<total; i++) {
   thumbnails* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
   thumbnails_fn(i);
  }
  
 } else {
  content = "file not loaded!";
 }
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
var pause3;
 
this.createEmptyMovieClip("tscroller", 1000);
scroll_speed = 20;
var tot = 0;
var fun1 = function(){
tscroller.onEnterFrame = function() {
   for (var obj in cliparray) {
    cliparray[obj]._x -= scroll_speed;           
   }
   if (cliparray[0]._x< -200) {
    cliparray[0]._x = cliparray[cliparray.length-1]._x+cliparray[cliparray.length-1]._width+10;
    var j = cliparray.splice(0, 1);
    cliparray = cliparray.concat(j);
   }
 clearInterval(pause1);
  
};
}
pause1 = setInterval(fun1,2000);
pause3 = setInterval(fun2,2404);
function fun2(){
 tscroller.onEnterFrame = null;
 clearInterval(pause3);
 pause1 = setInterval(fun1,2000);
}
pause3 = setInterval(fun2,2404);
function thumbnails_fn(k) {
 var yy = thumbnail_mc.createEmptyMovieClip("t"+k, thumbnail_mc.getNextHighestDepth());
 cliparray.push(yy);
 tlistener = new Object();
  tlistener.onLoadInit = function(target_mc) {
  target_mc._x = 5+(target_mc._width+10)*k;
  target_mc.pictureValue = k;
  tot += target_mc._x;
    
 };
 image_mcl = new MovieClipLoader();
 image_mcl.addListener(tlistener);
 image_mcl.loadClip(thumbnails[k], "thumbnail_mc.t"+k);
}
