How do I add Animations?

How would I show you guys an animation if I made one? I know how to post pictures, but how would I post an animation like, here? Also, what exaclty are sticky threads, and why are they, uhh, “sticky”? Thanks in advance!

The person in that thread made those animation a GIF I dont know howto and a sticky thread wont be pushed down the list of thread post it stays at the top

How can a thread be made, “sticky”? Why don’t more people have “sticky” threads?

I think members have to vote for the thread to become a sticky thread.

Thank you 3D Geek. But does anyone know how to upload GIF’s?
