I exchanged several e-mails with the administrator of the web-hosting service (www.pipni.cz) and it crashes: mandrake 2.4.19-7mdk + PHP 4.2.3 completely, including apache same on redhat on slackware 8.1 + php 4.2.2 only the script crashed, not whole server. Now to the script. I got this script from a Czech PHP course and there was a bug in the script. It creates a bitmap and then draws into the bitmap. The bug is the bitmap is too small, the coordinates used in draw and fill functions are beyond the size of the bitmap. And the fill functions that get the starting point outside of bitmap let it go down. Here is the script: <?php $width = 50; $height = 100; $ImHandle = imagecreate($width,$height); //Define colors $MyBlue = imagecolorAllocate($ImHandle, 0, 0, 255); $MyRed = imagecolorAllocate($ImHandle, 255, 0, 0); $MyWhite = imagecolorAllocate($ImHandle, 255, 255, 255); $MyBlack = imagecolorAllocate($ImHandle, 0, 0, 0); //Draw ImageFill($ImHandle,0,0,$MyBlack); ImageLine($ImHandle,20,20,180,20,$MyWhite); ImageLine($ImHandle,20,20,20,70,$MyBlue); ImageLine($ImHandle,20,70,180,70,$MyRed); ImageLine($ImHandle,180,20,180,45,$MyWhite); ImageLine($ImHandle,180,70,180,45,$MyRed); ImageLine($ImHandle,20,20,100,45,$MyBlue); ImageLine($ImHandle,20,70,100,45,$MyBlue); ImageLine($ImHandle,100,45,180,45,$MyRed); ImageFill($ImHandle,21,45,$MyBlue); ImageFill($ImHandle,100,69,$MyRed); ImageFill($ImHandle,100,21,$MyWhite); ImageString($ImHandle,4,40,75,"Czech Republic",$MyWhite); // Send to browser Header("Content-type: image/PNG"); ImagePNG($ImHandle); //Free resources imagedestroy($ImHandle); ?> Take care Honza ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19366&edit=1
