Check the BindingUtils class and its bindSetter method. You can bind a setter to the "width" property and adjust the x property of your image in that handler.

Considering that as3 is OO language i always start from something like this:

    public class App extends Sprite { 

        public function App() { //constructor   
            super();    //extends class constructor     
            loading();  //your function were you set all elements properties
        }
    }
