Loading Random Images...

Hi guys... I'm kind of desperate, I have my code working beautifully for loading in an image at full screen...

Code:

---

Stage.scaleMode = "noScale";
Stage.align = "LT";
import flash.display.*;

function loadBitmapSmoothed(url:String, target:MovieClip) {
        var bmc:MovieClip = target.createEmptyMovieClip("bmc", target.getNextHighestDepth());
        var listener:Object = new Object();
        listener.tmc = target;
        listener.onLoadProgress = function(target:MovieClip, bytesLoaded:Number, bytesTotal:Number):Void  {
                percent = Math.round((bytesLoaded/bytesTotal)*100);
                pText.text = percent+"%";
        };
        listener.onLoadInit = function(mc:MovieClip) {
                mc._alpha = 0;
                mc.onEnterFrame=function ()
            {
            mc._alpha += 15;
            if(mc._alpha >= 100)
                    {
                        delete this.onEnterFrame;
                    }
               
                var bitmap:BitmapData = new BitmapData(mc._width, mc._height, true);
                this.tmc.attachBitmap(bitmap, this.tmc.getNextHighestDepth(), "auto", true);
                bitmap.draw(mc);
               
                // set size and position on load
                if (Stage.height/Stage.width>target._height/target._width) {
                        img_prop = target._width/target._height;
                        target._height = Stage.height;
                        target._width = Stage.height*img_prop;
                        target._y = (Stage.height/2)-(target._height/2);
                        target._x = (Stage.width/2)-(target._width/2);
                } else {
                        img_prop = target._height/target._width;
                        target._width = Stage.width;
                        target._height = Stage.width*img_prop;
                        target._y = (Stage.height/2)-(target._height/2);
                        target._x = (Stage.width/2)-(target._width/2);
                }}
        };
        var loader:MovieClipLoader = new MovieClipLoader();
        loader.addListener(listener);
        loader.loadClip(url, bmc);
}
loadBitmapSmoothed("images/image1.jpg", bg_con);

// set size and position on resize
var stageL:Object = new Object();
stageL.onResize = function():Void  {
        if (Stage.height/Stage.width>bg_con._height/bg_con._width) {
               
                cover._x = Math.round(Stage.width - Stage.width);
                cover._y = Math.round(Stage.height / 2);
                address._x = Stage.width / 2;
                address._y = Stage.height - 30;
                header._width = Stage.width;
                footer._width = Stage.width;
                footer._y = Stage.height;
               
                img_prop = bg_con._width/bg_con._height;
                bg_con._height = Stage.height;
                bg_con._width = Stage.height*img_prop;
                bg_con._y = (Stage.height/2)-(bg_con._height/2);
                bg_con._x = (Stage.width/2)-(bg_con._width/2);
        } else {
               
                cover._x = Math.round(Stage.width - Stage.width);
                cover._y = Math.round(Stage.height / 2);
                address._x = Stage.width / 2;
                address._y = Stage.height - 30;
                header._width = Stage.width;
                footer._width = Stage.width;
                footer._y = Stage.height;
               
                img_prop = bg_con._height/bg_con._width;
                bg_con._width = Stage.width;
                bg_con._height = Stage.width*img_prop;
                bg_con._y = (Stage.height/2)-(bg_con._height/2);
                bg_con._x = (Stage.width/2)-(bg_con._width/2);
        }
};
Stage.addListener(stageL);

cover._x = Math.round(Stage.width - Stage.width);
cover._y = Math.round(Stage.height / 2);
address._x = Stage.width / 2;
address._y = Stage.height - 30;
header._width = Stage.width;
footer._width = Stage.width;
footer._y = Stage.height;
footer._y = Stage.height;

BUT now I want to be able to have random images loading... I had this previously but can't seem to implement it into the new code...

Code:

---

var myTest = random(6) + ".jpg"; // Load 1 of 6 random images

---

Also further down the timeline I want to be able to add an image I directly target which I have been able to achieve by placing this on the timeline...

_root.loadBitmapSmoothed("images/image1.jpg", _root.bg_con);

Any help would be greatly appreciated!
