I'm having some problems with get/putimage.  If the routines are in a small
program (say 10K), the work fine.  If they are within a 200K program,
something is amiss.  Perhaps some other buggy code is interfering with the
structures but I can't point it out.  

It would be helpful to have an idea on how to write our own get/putimage
routines, especially to handle images larger than 64K.
