Ok, I figured this out after a week, use the app Memmy’, they upload your images to imagur including GIFs, any way in the app create a new post, doesn’t matter where, then insert your gif, it will automatically upload it to imagur.
Once you have the link in the URL section (your uploaded image) copy it and create the post you want, where you want in the Lemmy website, you now have a GIF.
Complicated but it works, example over on c/weirdwheels.
How do you post Gifs?
I guess the title basically says it all. Anyone know how to post gifs, like you would post an image? Can you do that?...
