Cannot Set Image Size of XML Loaded Images

I’m Loading an image into a MC based on an XML file. I’m setting the initial alpha to 0, loading the image, then setting the alpha to 100 once I see that it is fully loaded. The problem is that I want the image to be resized, which is not working. Every time I check the size of the MC once the image is loaded I get 0x0. Here preload code.


function preload(num) {
	
	eval("image"+num).loadMovie(url[num],1);
	
	eval("image"+num).onEnterFrame = function() {
		
		var bytesloaded = this.getBytesLoaded();
		var bytestotal = this.getBytesTotal();
		var percent = Math.floor(bytesloaded/bytestotal*100);
		
		trace(this._width);
		
		if(percent >= 100 && this._width > 0 && this._height > 0){ 
			
			trace(this._width);
			this._alpha = 100;
			delete this.onEnterFrame; 
			
		}
	
	};
	
};
