resizing and centering the images

MovieClipLoader - yes, but you don't want to use bytes as a measure of
doneness. You use the onLoadInit method of the MovieClipLoader class, which
is fired once the target is downloaded and ready to use.

So, get rid of your loadMovie and use MCLoader, and its onLoadInit.

Simple example - assumes there is a clip with an instance name of holder in
the root.

var mcl = new MovieClipLoader();
var lis = new Object();
lis.onLoadInit = function(target:MovieClip){
target._x = 100;
target._y = 100;
target._width = 320;
traget._height = 240;
}
mcl.addListener(lis);
mcl.loadClip("full url of clip or image to load", holder);


That's all ya need. But if you want to add a progress bar to show the
download, you'd add a onLoadProgress method to the lis object.

everybody uses getBytesLoaded and getBytesTotal because you need to implement one preloader to make sure your images are loaded before you try to scale them

something like

if(getBytesLoaded() == getBytesTotal()) {
my_pic.xscale = 105;
my_pic.yscale = 125;
} else {
trace("not yet loaded");
}
