note 100566 added to function.imagepng

I'm trying to output an image to the browser, which works fine.. it displays as it should. The problem comes when saving the file (right click --> save as) It produces a corrupted png that can't be read. tested on chrome, firefox with win vista and win 7, all produce a corrupted png. imagesavealpha($finalImage, true); header('Content-type: image/png'); imagepng($finalImage,NULL,0,NULL); ---- Server IP: 69.147.83.197 Probable Submitter: 81.129.191.116 ---- Manual Page -- http://www.php.net/manual/en/function.imagepng.php Edit -- https://master.php.net/note/edit/100566 Del: integrated -- https://master.php.net/note/delete/100566/integrated Del: useless -- https://master.php.net/note/delete/100566/useless Del: bad code -- https://master.php.net/note/delete/100566/bad+code Del: spam -- https://master.php.net/note/delete/100566/spam Del: non-english -- https://master.php.net/note/delete/100566/non-english Del: in docs -- https://master.php.net/note/delete/100566/in+docs Del: other reasons-- https://master.php.net/note/delete/100566 Reject -- https://master.php.net/note/reject/100566 Search -- https://master.php.net/manage/user-notes.php
