note 53916 added to function.header

whenever I use header, like in <?php header('Content-Type: image/jpeg'); ?> similar to session_start, I cannot do anything above the "header" line, not even an include('header.php') otherwise it says "header already sent" so how do you get around that? I can't put <head> <title> </title> </head> etc before the "header()" tag or it gives me an error saying "header already sent" how do you get around this? ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53916 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53916&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53916&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53916&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53916&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+53916&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53916&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53916&report=yes Search -- http://master.php.net/manage/user-notes.php
