Despite the growing interest in Facebook, Facebook Connect as a way to integrate facebook identity and sharing features on any site around the web, one of the untold stories about sharing on facebook is the simple power of the facebook Share button.Facebook looks for a title, description, and thumbnail image to pull into the feed story. While facebook will always try to find this for any shared link, you can actually specify this copy for the facebook crawler if you want to have more control over the copy or images that show up in facebook.Facebook gives you the option to explicitly specify which image shows up next to content your users share. Facebook also makes it possible to add metadata to your page to make audio and video sharing more powerful.
