ActionScript 3.0 :: Controlling The Size Of An Uploaded Art File To Display On Movie?

I've got the following file reference listener on a file to upload art for display on a flash movie. However, I want this to display only at a certain size. I tried the "easy way", but this ends up sizing down my whole movie. Where should I insert the code to get the uploaded file to show on my flash movie only to a certain height and width? "chip_clip" is the empty movie clip this is being uploaded to:

var file:FileReference = new FileReference();
file.addEventListener(Event.SELECT, fileSelect);
file.addEventListener(Event.COMPLETE, fileComplete);

[Code].....
