Load an image, make it rotate - agh!

Jeez how hard can this be? I am giving up for now, but perhaps one of you can tell me why I can’t simply load an image into flash and rotate it using AS…
[note: image is 700x700 pixels in size]
Oh it loads all right, but it will not rotate around its center. I know it loads the image in at the top left corner, but I thought the following code would fixt that:


this.createEmptyMovieClip("george", 0);
george._x = 0;
george._y = 0;
george.createEmptyMovieClip("george2", 2);
george2._x = 700;
george2._y = 700;
var myMCLoader:MovieClipLoader = new MovieClipLoader();
myMCLoader.loadClip("images/ultimateEarth.gif", george.george2);
trace("image");
george.george2._xscale = 50;
george.george2._yscale = 50;
onEnterFrame=function():Void{
    george._rotation += 5;
}

I’ve changed the code around so much that what is here may not be the best I’ve come up with so far…
