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,

Is there anything wrong with just using $_FILES['upload_name']['type']?
