Getting the “real” Facebook profile picture URL from graph API

Question

Facebook graph API tells me I can get a profile picture of a user using

http://graph.facebook.com/517267866/picture?type=large

which works fine. However, whe

Answer 1

$url = 'http://graph.facebook.com/100000771470028/picture?type=large';
$rray=get_headers($url);
$hd = $rray[4];
echo(substr($hd,strpos($hd,'http')));

This will return the url that you asked, and the problem of changing the url by facebook doesn't matter because you are dynamically calling the url from the original url.
