There are a number of different ImageConsumer objects that will attach
themselves to you for any number of different reasons. An "InfoGrabber"
object will attach itself to you when you first create the image so that
it can catch the width, height and any properties you may report. It
will remove itself at the first imageComplete, whether it is FRAMEDONE
or STATICIMAGEDONE.
The first time you try to draw the image using drawImage, you will get
an "ImageRepresentation" object attached to you which will handle the
conversion of the pixels for the screen...
