Problem getting binary data over http

Hello List!

I am trying to get images with a little script over http.
But the data that is written on my harddrive is corrupted :-(

Is this a lame question? Does anyone know how to do it better? Is this a
bug?

Here a little snippet to test:

<?php

$fp = fopen("http://www.php.net/gifs/logo.gif","r");

$Image = fread($fp,150000);

$fp2 = fopen("logo.gif", "w");

fwrite($fp2,$Image,150000);

fclose($fp2);

?>
