AS3 - Convert String to Bitmap

I'm trying to store my images on a server to lighten the load of my SWF file. I've spent all day trying to get the data from the server, but all I get is a seemingly random string (which I understand is the string value of my image). I've tried reading up on this, but I haven't found anything that actually works, I get a lot of references to Base 64 encoding/decoding and I've tried a couple of libraries but they do nothing. Here's what I have (I've simplified it a bit to upload it):

public function loadImage() : void {
    var url:String='example.com/some_image';
    var load:URLLoader=new URLLoader(new URLRequest(url));
    load.addEventListener(Event.COMPLETE, onLoadComplete);
}

public function onLoadComplete(event : Event) : void {
    var imgString:String=event.target.data;
}

But how do I convert imgString to a Bitmap or Sprite so I can addChild() it? I've tried imgString as Bitmap which returns null. Maybe it has something to do with the BitmapData class? This post seems similar but is unanswered.

If you have a server that runs PHP, you can generate the image first, e.g.

// PHP script 'http://yoursite.com/image.php
header("Content-type: image/jpeg");
echo $myImageDataFromDB; // Get the image data from MySQL.

And then in ActionScript, use the standard process to load that as an image:

var request:URLRequest = new URLRequest("http://yoursite.com/image.php");
var loader:Loader = new Loader();

loader.load(request);
addChild(loader);
