Images are strange, because you get back an object immediately, but they
load in the background.  So just because you got back a result from
getScaledInstance doesn't mean it has finished loading yet.

Before you draw it, you should make sure it has loaded.  The best way to do
that is with a MediaTracker.  Something like this will work.

    MediaTracker tracker = new MediaTracker(this);
    tracker.addImage(scaledImage, 0);
    tracker.waitForAll();

Once you get this working, you should probably only get a new scaled
instance when the frame's size changes and keep it cached so you can
repaint with the same image object each time.  Otherwise every time your
component needs to repaint, you'll be waiting for the image to be processed
which will introduce some sluggishness in the response.
