Error am getting OAuthException: (#100) picture URL is not properly formatted

I have got a very strange problem,I am able to upload pictures on my page album using graph api,but when i try to post a picture using graph api,it is not working,

Note when i post a message or a link to wall,its getting posted,the problem is only with the picture.

Here i am putting both the code snippets:

1,This is when i am trying to upload a picture to page album(working):

$facebook->setFileUploadSupport("http://apps.facebook.com/pagecron");
$x=realpath($_FILES['source']['tmp_name']);
$parameters = array('message' => $_POST['message'],'source' =>'@' . $x );
$parameters['access_token'] = $_SESSION['active']['access_token'];
$check=$facebook->api('/'.$_SESSION['active']['id'].'/photos/','POST',$parameters);

2,This is when i am trying to post a picture to the wall(Not Working):

$img = realpath($y);
$facebook->setFileUploadSupport("http://apps.facebook.com/pagecron");
$x=realpath($_FILES['source']['tmp_name']);
$parameters = array('message' => $_POST['message'],'picture' =>'@' . $x );
$parameters['access_token'] = $_SESSION['active']['access_token'];
$check=$facebook->api('/'.$_SESSION['active']['id'].'/feed/','POST',$parameters);

Answer 1

Ist Thing: You need to POST to /TIMELINE_PHOTOS_ALBUM_ID/photos.

2nd Thing:There may not be an album with such a name,so you should ist create it(After checking).

How To:

 $albums =$facebook->api('pageid/albums',GET,array('access_token'=>'access_token');      
 foreach($albums['data'] as $album)
 {
   if($album['name'] == 'TIMELINE_PHOTOS')
   {
      $uid = $album['id'];
   }
 }
if(isset($uid) && $uid !=0)
{
  //mean album is there so use that uid to post your photo
}
else 
{
    //create your album with that name and use its id
}
