如何更改 facebook 推荐的文字、链接或缩略图？

Question

When a user recommends my link (which has content, images, etc) it only displays the site name as the link with no text or images. How can I edit it so it does so?

My code is as follows;

<div id="fb-root"></div> 
<script src="http://connect.facebook.net/en_US/all.js#appID=1234567890&xfbml=1"></script> 

   FB.Event.subscribe('edge.create', function(response) {
        //replace the next line with calling your div
        alert('Shared!');
   });
 </script>
 <fb:like href="http://www.mysite.com/" send="false" width="450" show_faces="true" action="recommend" font=""></fb:like>

Answer 1

Add open graph meta tags to your page so it knows what to pull in. https://developers.facebook.com/docs/opengraph/

Answer 2

On http://www.mysite.com/ , add the og:image meta tag for an image and og:description to customize the text.

There's a linter tool that checks whether you did it right: http://developers.facebook.com/tools/debug
