I have included both the palette and source that 
generated the palette.  

The palette provides a few buttons for changing 
the ImageRegion option of a cell that contains 
graphics.

This will allow you to zoom in/out of a rendered 
postscript image.  This also allows you to move the
image around.

This palette works as follows:

1.) Make sure the frontend has a kernel connected to it.    
    The front end will have a kernel after you evaluate
    something.

2.) Select a cell that contains a graphic rendered 
    by the frontend.

3.) Click on one of the buttons of the palette to 
    change what part of the image you look at.
