fb.ui({ method: 'send', link: 'http://myurl.com/home/pagetoshare', picture: 'http://myurl.com/home/getimg?imageid=1', name: 'shared page', caption: '', description: '' }, function (response) { });

and error message get:

an error occurred. please try again later.

api error code: 100 api error description: invalid parameter error message: picture url not formatted
