The read/write operation to the database for these is expensive and unnecessary. Store a reference to the image instead, which can be quickly and easily called. Also, a 2Mb image file...even on an intranet this is just wrong unless you have a need for high-res photos. If someone accessed this on a dial-up it would cause them avery long wait indeed. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
