I test your script it work fine for me, just remove the useless double quote and dot for $image.

<?
$image ="http://cdn.sstatic.net/stackoverflow/img/sprites.png?v=5";
$rename="123";

$ch = curl_init($image);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$rawdata=curl_exec ($ch);
curl_close ($ch);

$fp = fopen("$rename.jpg",'w');
fwrite($fp, $rawdata); 
fclose($fp);
?>
