I think rtrim() is probably your best bet.

Point the <img> tag at a PHP script which pulls it out of $_SESSION and renders it as an image. Then you don't need to send it to the client in any form. -- Jasper Bryant-Greene General Manager Album Limited e: jasper@xxxxxxxxxxx w: http://www.album.co.nz/ p: 0800 4 ALBUM (0800 425 286) or +64 21 232 3303 a: PO Box 579, Christchurch 8015, New Zealand -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
