   var publish = 

    {
              method: 'stream.publish',
              message: 'Some kind of test',
              uid: uid,
              attachment: {
                name: 'Test',
                caption: 'Facebook API Test',
                description: ('Sure hope it worked!'),
                href: 'http://www.test.com/',
                media: [
                  {
                    type: 'image',
                    href: 'http://test.com/',
                    src: 'http://test.com/image.jpg'
                  }
                ]
              },
              action_links: [
                { text: 'Your text', href: 'http://www.test.com/' }
              ],
              user_prompt_message: 'Share your thoughts about test'
    };

    publish.target_id = friendID;
    FB.ui(publish);

    publish.target_id = friendID;
    FB.ui(publish);

            return false;
