Hey all,

I just checked, and the GIF patent supposedly expires June 19, 2003. 
Also, it's not even clear that programs that just display GIF images are 
encumbered by the patent -- many argue it's just those that create GIFs. 
So, since so many people still use the format, it doesn't seem like a 
big deal to make it an option.
