If you have issues with images not generating in the console or your published site, your server may have alternate image processing libraries available that may work better with Koken.
Sign in to your Koken install and visit Settings > Image publishing. If your server supports additional image processing libraries, you will see a menu with those options. Select a different option, then click the Save button at the bottom of the screen. Koken lists the image processing libraries in the preferred order, so try them from top to bottom until you find one that works well for you.
Supported image processing libraries
Beginning with version 0.16, Koken supports the following image processing libraries:
- Imagick PHP extension
- GD (bundled with most PHP installations)
