Resizing External JPG's

programming flash
1

I have a slideshow that loads external jpg’s but i need them to fit the mc holder i made. can I get Flash to automatically resize the external jpgs?
Here is my code for the slideshow:

var x:XML = new XML();
x.ignoreWhite = true;

var urls:Array = new Array();
var captions:Array = new Array();
var whoIsOn:Number;

x.onLoad = function(success) {
var photos:Array = this.firstChild.childNodes;
for(i=0;i<photos.length;i++) {
urls.push(photos*.attributes.url);
captions.push(photos*.attributes.caption);
}
holder.loadMovie(urls[0]);
caption.text = captions[0];
whoIsOn = 0;
}

x.load(“lost.xml”);

previous.onRelease = function() {
if(whoIsOn > 0) {
whoIsOn–;
holder.loadMovie(urls[whoIsOn]);
caption.text = captions[whoIsOn];
}
}

next.onRelease = function() {
if(whoIsOn < urls.length-1) {
whoIsOn++;
holder.loadMovie(urls[whoIsOn]);
caption.text = captions[whoIsOn];
}
}
