When I rightclick on my class to set an image (from the greenfoot preset images) e.g. as the background the image is not displayed I tried this with other classes and images aswell but none of them are displayed.
You can try to copy the image into your scenarios folder and then set it using code. I believe the images are somewhere in your Greenfoot installation in the folder lib/greenfoot

The actors' images should change when you "Reset" the scenario.
