I am doing some operations on a number of images, which are all of
different sizes.  One thing I want to do is to split each image
up, and extract four subimages, one for each quadrant of the 
original.  I can do that with vextract *AS LONG AS I CAN FIND
OUT THE SIZE OF THE ORIGINAL IMAGE AND MAKE IT AVAILABLE TO
VEXTRACT WITHIN MY PROGRAM*.  Any ideas on how best to achieve
that?
