createImage is a factory method that creates a concrete instance of a class
that extends java.awt.Image. Different VM's will create different concrete
classes and may implement the methods differently, but you can rely that all
the methods defined in the Image class are at your disposal.  For fun you can
print out the name of the actual class created with System.err.println("the
image is of class " + im.getClass().toString());
