I apologize if I'm just being stupid about this, but I take this opportunity to ask: how do we add alt-text to an image on Lemmy? I always add it on Mastodon, but I've never figured out how to do it on Lemmy (I use the web interface, maybe it requires a special app?). I've seen that others have done it, and I see that it's a rule here for images of text, which is good. But HOW to do it?
Thanks!
Edit: Thanks everyone for the answers!
