Using Gifs in Comments?

Can we use Gifs and Images in the comment section?? If yes then how?

Are you using gifs in the comments too? It's really a fun way to give replies in comments, right?

Someone send this gif in my comment and I really like it but I don't know how to send gifs in comments.

By copy-pasting from browser to comment or what?

Tell me if you know how can I use them in the comments?
