posting photo to facebook raises exception

i wrote a function to post a photo to a users wall and it raises the following exception

Fatal error: Uncaught OAuthException: A user access token is required to request this resource. thrown in C:\xampp\htdocs\upd8r\application\helpers\base_facebook.php on line 1039

this is my code- what am i missing?

function facebook_img_post($fb_id,$data){


        $this->load->helper('facebook');

        $this->load->model('mmaster');
        $globalSettings = $this->mmaster->getGlobalSettings('1');

        // Create our Application instance.
        $this->facebook = new Facebook(array(
          'appId'  => $globalSettings['facebook_id'],
          'secret' => $globalSettings['facebook_secret'],
          'cookie' => false
        ));

        $this->facebook->setFileUploadSupport(true);


        $this->facebook->api("/".$fb_id."/photos",'post', array(
                'message'=> $data['message'],
                'source' => $data['source']
            )
        );





        //new fb post

    }

update

this is the link the user registered with showing all the permissions requested

$data['loginUrl']   =   $this->facebook->getLoginUrl(array('scope' => 'read_stream,publish_stream,status_update,offline_access'))

update 2

I swapped the api out and tried it with curl to have more control and apparently i need a user access token- even though i was retrieving and using an application access token- apparently there are two different ones.

You need to have the user grant you publish_stream and manage_page permissions also to do this when you get the loginURL, e.g.

$loginUrl = $facebook->getLoginUrl(
    array(
        'scope' =>'user_status,user_photos,status_update,manage_pages,publish_stream,offline_access',
        'redirect_uri'  => $fbconfig['baseurl']
        )
);

Here's some more info: FB permissions: http://developers.facebook.com/docs/reference/api/permissions/

you need to request an access token with publish_stream permission

check out this links:

UPDATE

after creating an instance for new Facebook you have to redirect to the FB for user authentication:

$loginUrl = $this->facebook->getLoginUrl(array('scope' => 'publish_stream, offline_access'));
echo '<script>top.location.href="'.$loginUrl.'"</script>';

second update

if you're doing all in this way and the problem still exists, then maybe you're passing the image data to curl incorrectly. You must prepend image path with @ to inform CURL that it must send the image as multipart data.
