You can get the URL of the thumbnail from the youtube page and then enter that URL in the “thumbnail URL” text-box when creating/editing your post.

Tangentially related: how do I make YT thumbnails (or any thumbnail, for that matter) show on Lemmy posts?

The thumbnail shows up just fine on Voyager FWIW.

Uh. I never see thumbnails on my posts on either my app (Lemmy) or pc (either the standard lemmy site or Alexandrite). Maybe Voyager has a built-in functionality that allows it to fetch the thumbnails frok YT when they are missing in the post itself?
