When I attempt to upload a new header image to my wordpress installation my browser's work is acknowledged with a cryptic "Image could not be processed. Please go back and try again." The upload does succeed: wp-content/uploads/.../header.jpg exists as it should.

There are no error messages in /var/log/messages--which php is configured to log errors to--nor in nginx's error log. This setup was previously discussed here.

My setup:

  • Wordpress 3.0.4
  • Twenty Ten 1.1
  • nginx 0.8.54
  • php-fpm 5.3.5 (fpm-fcgi)
  • Arch Linux

You might not have the gd library installed and enabled in php. I'm not much of an Linux guy, but I did this to get it installed on my setup:

yum install php-gd

Here's some more about it:

Don't forget to restart httpd after installing gd.
