ActionScript 3.0 :: .target.content Works Offline, But Not On Server?

I've set up an event listener to check if an image has been loaded. If yes, then change the width and height of it. I achieved this by using .target.loader.content. It works fine on my machine, but things are different, when I upload the swf to the server. the images get loaded, but aren't resized as they were offline. What might be causing this? What changes should I do in the snippet to get it working.This is the function that is called using the eventListenerfunction setImage(evt:Event){  sig_txt.text =evt.currentTarget.content.toString();  var loader:Bitmap = evt.target.loader.content as Bitmap;  gallery_mc.addChild(loader); var ratio:Number = loader.width / loader.height;  loader.width = 100;  loader.height = 100 / ratio;  loader.y = total_height;  total_height += loader.height + 20
