GIF's for animation WIP thread?

Hello! I want to make a WIP thread over a short simple animation that I’m doing. Clearly I will need to be posting sequential images instead of single frames. Problem is that since I can’t post regular movie files, I have to upload it to my youtube but I don’t want all these Work in progress videos on my channel. Is there a way I can import a GIF on a thread? If so can anyone give me tips on how to make one?
