I want to programm chess, but without Greenfoot. I make that with blueJ and "Java-Editor". Therefore I need to paint the images of the fields. But I don't want to paint an image for every possible comination (white king ond white field - white king on black field - black king on white field - black king on black field... -> 6*4=24 images). I want to paint the images if the figures onto an ImageIcon, which has an black image of 50px X 50px or a white image with the same dimensions (a field). So I need a method like the drawImage method in GreenfootImage only for class ImageIcon. Any suggestions?

In my 'Chess: Drag-n-Drop' scenario, I did not use any actual images for the pieces. I used (char)9812 through (char)9823 as text for the piece images. Maybe you can do something with them, since they can be used in String objects (as opposed to image objects).

I downloaded it to know more about it. It's interesting to see, that such Characters exist.

Then I can use the setText method of my JButtons. Thank you.

A little suggestion for improvement: wouldn't JLabels be better for the fields on the chessbord? I think that would make it look more like a chessboard. A JLabel can also reakt on mouse events like a JButton. When it's clicked by the mouse it would have the same reaction. For example you could use some code like this for the labels: 
JLabel label = new JLabel("Some text or Symbols");
label.addMouseListener(new MouseAdapter() {
    @Override
    public void mouseClicked(MouseEvent arg0) {
        //this method will be executed when you click on the field.
        //almost like buttons.
        System.out.println("mouseEvent");
    }
});

Thanky, but because I painted an own image, which is only black they don't look like buttons any more. I didn't know that JLabels can be used as buttons, too, but I don't want to change it all, because all 64 fields (I have made a class "Feld" for them) are JButtons and in the GUI class they aren't saved in an array or a list like I wanted that first. I've enumerated them like: JButton jButton1 = new JButton(); JButton jButton2 = new JButton(); JButton jButton3 = new JButton(); That's very ugly, but I don't have much experience with that. My try to use an Array and to save them with a for-loop wasn't lucky because the actionListener didn't like it and I wasn't able to fix that. I hope you understand now.
