Hi there, I was posting on [email protected] for a while, and I’d post links to youtube videos, and it’d automatically make thumbnails so that was cool.

But then “something changed” and it no longer made thumbnails, at least when seen on the web interface. But sometimes it does? The following image shows an example. In the first post, it has no thumbnail but in the second case it does:

MY QUESTION: how do make a Lemmy post to a video (especially on youtube) such that the post includes a thumbnail?

• Either automatically-generated, or custom-made by me.
• Preferrably via a computer client rather than phone.
