Hvorfor laver den ikke unklink?

Scriptet her virker tildels....
Den sletter fint i mysql databasen, men den unlinker ikke billedet!

<?php
mysql_pconnect("localhost","***","***");
mysql_select_db("***");
if(isset($_GET['id'])) {
    $query = mysql_query("SELECT * FROM billeder WHERE id='$_GET[id]'") or die(mysql_error());
    $row = mysql_fetch_array($query);
    if ($row['imgsrc'] == 'no_pic.jpg') {
    mysql_query("DELETE FROM billeder WHERE id='$_GET[id]'") or die(mysql_error());
    echo "kun slettet info";
    } else {
    mysql_query("DELETE FROM billeder WHERE id='$_GET[id]'") or die(mysql_error());
    @unlink($row['imgscr']);
    echo "slettet alt!";
    }
    }
?>
