I will quote GPL again.
To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
2. You may modify your copy or copies of the Program or any portion
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.
If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.
This plainly states that if recipient can't modify .gif in every
way he/she want, you can't distribute GPLed file to him/her.
