Then check the different formats that are offered - they include larger pictures. — CBroe, Dec 05 '13 at 13:46

you can use this php code, its working for me.

<?php 
   $video_id = "10153231379946729"; 
   $xml = file_get_contents('http://graph.facebook.com/' . $video_id); 
   $result = json_decode($xml); 

   $small = $result->format[0]->picture; 
   $medium = $result->format[1]->picture;

   //fetch the 720px sized picture
   $large = $result->format[3]->picture; 
?>

<img src="<?php echo $medium;?>">
