Here's the problem.  I'm initializing my VGA to 256 (320x200) colors
using Borland's bgi.  I'm displaying a GIF by shelling
out and executing a GIF viewing program.  I modified the program slightly
so that on completion it doesn't clear the screen.  When the program
terminates, TP uses a getimage to grab the screen.  I then write the
memory block out to disk using blockwrite.  So far so good.  Here's the
problem (really this time).  When I load the picture back in again
using blockread and then display it on the screen using putimage, my
palette is obviously not the same as it was after termination of the GIF
viewing program (it must set the palette).  So how can I save a
256 color palette along with the picture so that I can load it in
again at a later time.

Excuse the run on sentences but its been a looong day.

Thanks for any help that you can give,
