Oliver, Let's start with the fopen(), where the mode expression might be causing problems - should it be "rb"? http://www.php.net/manual/en/function.fopen.php If the 'binary' component hasn't been recognised it might explain the "first mistake". The ensuing problems may even stem from there... Regards, =dn
