If you include a link within a Mastodon post, it will automatically show a "link preview" below the post. Link previews often show an image associated with the link and/or basic information about the contents of the link.
You don't have to do anything special, the preview is generated automatically. It may sometimes take a few minutes to appear if your server is busy.

Weird... Tyee preview links work okay for me on the website interface? Are you using Mastodon through the website on desktop?
YouTube is another issue, a lot of people have had trouble getting it to embed as YouTube was doing something weird that other sites don't do.
