According to what Alex Khimch alex wrote at 19-Mar-2011 09:41 his random based image noise generator will not be random. There was a simple mistake in variable naming. Correct code would be: <?php header("Content-type: image/png"); $img = imagecreatetruecolor(500,500); $ink = imagecolorallocate($img,255,255,255); for($i=0;$i<500;$i++) { for($j=0;$j<500;$j++) { imagesetpixel($img, rand(1,500), rand(1,500), $ink); } } imagepng($img); imagedestroy($img); ?> ---- Server IP: 195.114.0.19 Probable Submitter: 91.194.188.90 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/106252 Del: integrated -- https://master.php.net/note/delete/106252/integrated Del: useless -- https://master.php.net/note/delete/106252/useless Del: bad code -- https://master.php.net/note/delete/106252/bad+code Del: spam -- https://master.php.net/note/delete/106252/spam Del: non-english -- https://master.php.net/note/delete/106252/non-english Del: in docs -- https://master.php.net/note/delete/106252/in+docs Del: other reasons-- https://master.php.net/note/delete/106252 Reject -- https://master.php.net/note/reject/106252 Search -- https://master.php.net/manage/user-notes.php
