Problem with post a picture in Facebook Wall with Graph API

问题

I am using the Graph API for Facebook in order to post a message and a picture through my application to the user's wall. I use this one:

$facebook->api('/me/feed', 
               'post', 
               array( 
                 'access_token' => $token, 
                 'message' => $message, 
                 'caption' => $caption, 
                 'description' => $description, 
                 'picture' => $picture, 
                 'cb' => ''
                )
              );

This works fine for around 4-5 months now. Suddenly I cannot post the picture. I haven't changed my code at all, but now I cannot see the image that is supposed to be posted.

I really don't know what is the problem. I would really appreciate any help!

Thanks in advance

May be you need to use rawurlencode to pass google chart api url. As that consist of many special characters.

The feed will only allow you to upload small images. Try a small image, if it works your probably need to post as image instead of wall post.
