There are a few, but not very active ones.

Lemmy world seems to have the most active one:

!gifs@lemmy.world

Edit: removed the obviously dead community

Because there are like 5 active posters between every instance.

You only get pugs Jesus and butterfly posting their content, and news here.

That's actually interesting that there isn't much of a gifs community around here. I've never particularly noticed before either. Even that lemmy.world community looks kinda dead on my end. And it's not like it's a niche subject or anything.
