If you can provide the image you tried with, that would help a lot. Also the configure line you used to configure PHP helps. ------------------------------------------------------------------------ [2003-09-10 15:36:55] derick@php.net Thank you for this bug report.

Reproduce code: --------------- $pic1 = imagecreatefromjpeg("my.jpg"); // 100x100px $pic2 = imagecreatetruecolor(100, 100); imacecopy($pic2, $pic1, 0, 0, 0, 0, 100, 100); imagecopymergegray($pic2, $pic1, 0, 0, 0, 0, 100, 100, 50); imagejpeg($pic2,"my2.jpg"); imagedestroy($pic2); Expected result: ---------------- my2.jpg - slightly saturated version of my.jpg. Actual result: -------------- a crash. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25476&edit=1
