GIF Unisys patents

What is the deal with GIF?
Is it a free source thing, or do i ahve to pay? Can i write my own Gif compression (not likely LOL) or can I buy a third party control?
If i can write my own.... anyone got any pointers?

UNISYS holds the patent on GIF compression. They are being very strict on enforcing that patent. Essentially this means that you can use GIF but if it becomes popular enough, they can sue you.

As for how to do GIF, I'd start by checking out the file format. Try the links in the Tutors Corner. I seem to recall a link there that had all kinds of file formats....
