let's assume your movieclip that has loaded the image is called pic_holder
you set it's width and height via pic_holder._width pic_holder._height properties
but i guess you have already tried this and your problem is that it doesn't work. the problem, most likely is that you are trying to resize it before the image has loaded. therefore you must resize the image after it's loaded.
therefore you may
a) either loop continuously and check to see if it's loaded or not
b) add an event listener that will call the resizing function when the picture is loaded
a)
this.pic_holder.onEnterFrame = function(){
if(this._width>0){
this._width=...your width...
this._height=...your height...
this.onEnterFrame=null;
}
}
b) extracted from as2 language reference. note that we are using loadClip instead of loadMovie
var loadListener:Object = new Object();
loadListener.onLoadComplete = function(target_mc:MovieClip, httpStatus:Number):Void {
target_mc._width=...your width...
target_mc._height=...your height...
}
var mcLoader:MovieClipLoader = new MovieClipLoader();
mcLoader.addListener(loadListener);
mcLoader.loadClip("..path to image..", pic_holder);
