In AS3, loading external images dynamically is done slightly differently than in ActionScript 2. Whereas in AS2, we could just use the loadMovie() method of the MovieClip class, this is no longer the case. Instead we have to use the Loader class, as well as the URLRequest class. This actually gives us more flexibility when loading external images, because of the various events of the Loader object that we can create event listeners for.
