sizing an empty movie clip

Hi There,
I have an instance of an empty movie clip object (imageLoader) to which I load
a .jpg image from an external file, as per the attached code . . .

But I have a problem in that I do not know the dimmensions of the .jpg image
before I load it and in some cases this results in a large image covering most
of my screen, including some of the text on the screen, I simply can't have
this as it looks crap for a start!

So, my question is this . . . How do I force the image pulled in from the
external file, and/or the movie clip object, to be no larger than a certain
size (i.e. H: 177 pixels x W: 177 pixels)?

function startLoading() {
var VoucherNo:String = this._parent.Connect_Check.VoucherNo;
var iNumOfTracks:Number = this.AlbumDetails.firstChild.childNodes.length;
//27 childNodes
var a:Number = Number(iNumOfTracks - 5);
var xmlArtist:XMLNode =
this.AlbumDetails.firstChild.childNodes[a].childNodes[0].firstChild.nodeValue;
var Artist = xmlArtist.toString();
var t:Number = Number(iNumOfTracks - 6);
var xmlTitle:XMLNode =
this.AlbumDetails.firstChild.childNodes[t].childNodes[0].nodeValue;
var Title = xmlTitle.toString();
var imagePath:String = ("C:\\local audio\\" + VoucherNo + "\\" + Artist +
"\\" + Title + "\\folder.jpg.jpg");
if(imagePath.lastIndexOf(":") != 1) {
var i:Number = Number(imagePath.lastIndexOf(":"));
var newImagePath = imagePath.substr(0, imagePath.lastIndexOf(":")) +
imagePath.substr(imagePath.lastIndexOf(":") + 1);
trace(newImagePath);
trace(i);
}
else {
var newImagePath = imagePath;
trace(newImagePath);
}
var mImageLoader:MovieClipLoader = new MovieClipLoader();
mImageLoader.loadClip(newImagePath, imageLoader);
}

I've solved this myself by using the "Loader" component to load the image to,
inside of an empty Movie Clip. The Loader component has a parameter property
called "scaleContent" which you set to "true". This automatically resizes any
image pulled in to the size of the Loader component as you yourself have scaled
it on your screen. Brilliant! Simply brilliant!

I guess Loader will work fine for you, but you might want to have a look
at the loadInit method of the MovieClipLoader class. That will allow you
to do what you want also - you just size your holder clip to whatever
you like - the trick is that you need to wait until the new clip is
fully loaded and instantiated - exactly what loadInit does for you.
