Solution

if you want to save your complete class diagram as an image, just click somewhere inside the editing pane and press Ctrl+A to select all classes in the diagram. Now you can copy the diagram to clipboard with Ctrl+C and paste it into your favorite image editing program with Ctrl+V to get your complete class diagram as an image. You could even select only some of the classes to get an image of a part of the diagram.
