The captcha plugin shows a real straight forward image. I believe that this type of image is of no use any more to hold back bots.
Geeklog.net has a nicer one and more sophisticated. How can I change the image?

Anybody?

The plugin uses static graphics by default. You can configure it to use dynamic graphics by switching the "Graphics Driver" to gdlib or ImageMagick in the plugin's configuration.
