Hi, Thanks to take care of this Stefan. As I understand your problem, you use directly Sextante source tree in your project, not bundled jar files. In the Sextante source tree, images are in their own directory, not in src/ directory. Probably the reason why they are not found by the classloader. I think you have - either to use Sextante compiled jar files (or do you intend to modify core Sextante classes ?) - or to add images directory in the classpath (not sure it is enough) - or to move Sextante images directory inside the src/ tree
