Hi, In my web application, end user is able to load images (png, jpeg, gif,..) into database. I would like to know how can i detect automatically the type of image (pnd, jpeg,...) ? i do not want to check the extension because this is easily faked... just by renaming it. Does it exist a technique for that ? thanks a lot, -- Alain ------------------------------------ Windows XP SP2 PostgreSQL 8.1.4 Apache 2.0.58 PHP 5
