CS4 or CS5 AS3 Loading images from library referenced in an array

[I_feel_dumb]

I have 28 jpegs in my library. I want to call them as needed from an array.

This code works fine for 1 image.

var myPic:Bitmap = new Bitmap(new pic1);
var scaleFactor:Number = 0.35;
var newWidth:Number = myPic.width * scaleFactor;
var newHeight:Number = myPic.height * scaleFactor;
var scaledBitmapData:BitmapData = new BitmapData(newWidth,newHeight,true,0xFFFFFFFF);
var scaleMatrix:Matrix=new Matrix();
scaleMatrix.scale(scaleFactor,scaleFactor);
scaledBitmapData.draw(myPic,scaleMatrix);
myPic.bitmapData = scaledBitmapData;
pic_holder.addChild(myPic);

When I try to replace the first line with an array reference like this...

var myPic:Bitmap = new Bitmap(new myArray[0][8]);

I get this error....

TypeError: Error #1007: Instantiation attempted on a non-constructor.

How can I easily reference the picture from my array. I have 28 arrays nested in another array. Each nested array contains strings, a sound and a jpeg

Thanks.
