I have now got it to work using the PixelGrabber class as follows:

    // initialise the Image object
    Image gif = Toolkit.getDefaultToolkit().createImage(imageData);

    // initialise a pixel grabber
    PixelGrabber pg = new PixelGrabber(gif, 0, 0, gif.getWidth(null),
gif.getHeight(null), true);

    // grab the pixels
    try
    {
      pg.grabPixels();
    }
    catch(InterruptedException ie)
    {
      ie.printStackTrace();
      throw new GifReaderException("PixelGrabber was interrupted while
reading from GIF Image bytes");
    }

    // retrieve the pixels from the grabber
    int[] pixels = (int[])pg.getPixels();

And now the pixels array contains RGB data, which I can inspect to my
heart's conent :)  I still dont quite understand the way the image loading
works, but there's no rush to find out anymore either.
