Thanks, Alex
I'm not sure how Facebook does it, but the content you are seeing is the <title> of the page:
<title>
Welcome to Facebook - Log In, Sign Up or Learn More
, the <meta name="description">:
<meta name="description">
Facebook is a social utility that connects people with friends and others ...
and the image in the <meta property="og:image">-tag:
<meta property="og:image">

One way of obtaining these is to create a script, a web crawler, that "scans" a page and identifies the tags you are interested in and grab their content.
