Can you post a sample script?

This might be a bug in GD 2.0 (just guessing). It's still a beta. You can try using the php_gd.dll from the PHP-4.0.5 package (see http://www.php.net/downloads.php) with PHP-4.0.6.

Have you tried the php_gd.dll from 4.0.5? If not, please do that.

And if that doesn't work, please make a SHORT sample script which reproduces your problem and post it here.

No feedback. Closing.

you should use imagecreatetruecolor() at line...

$dst_img = imagecreate($new_w,$new_h);
