Why would you want to keep track of them?

Just write a program that does what you want it to do
(resize, save, etc.) and send it forth from your other
program. When the user is finished with it, he or she
will kill it. What do you care?

Make sure you call the program with a Group_Leader, which
will be the top-level base of your GUI. Then, when your
GUI dies, all the programs that were spawned from it
(however many are still left!) will be destroyed, too.

Cheers,

David

P.S. You could use cgWindow to display your image profiles,
for example, then you already have all the resizing and saving
built right in. You really don't have anything at all to do,
except fill up the windows with the right commands.
