note 113515 added to function.imagepng

If you are outputting a PNG directly in response to a client request it is important to check your web server configuration. Some clients may request your images with a <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html">accept header</a> of image/*. Default configurations of Apache and possibly other servers will by default NOT allow your script to run in response to this request. Apache is specifically discussed at http://stackoverflow.com/q/19169337 but other server have been documented to have issue too. In other words, when testing your application don't just use the web browser, consider a phone's browser and networking libraries which could send different headers. ---- Server IP: 69.147.83.199 Probable Submitter: 173.12.28.129 ---- Manual Page -- http://php.net/manual/en/function.imagepng.php Edit -- https://master.php.net/note/edit/113515 Del: integrated -- https://master.php.net/note/delete/113515/integrated Del: useless -- https://master.php.net/note/delete/113515/useless Del: bad code -- https://master.php.net/note/delete/113515/bad+code Del: spam -- https://master.php.net/note/delete/113515/spam Del: non-english -- https://master.php.net/note/delete/113515/non-english Del: in docs -- https://master.php.net/note/delete/113515/in+docs Del: other reasons-- https://master.php.net/note/delete/113515 Reject -- https://master.php.net/note/reject/113515 Search -- https://master.php.net/manage/user-notes.php
