		getContentPane().add(listScroller,BorderLayout.CENTER);

		JPanel actionPanel = new JPanel();

Personally, I would create a seperate class that extends JPanel and add it to the other class:

import javax.swing;

public class ImagePanel extends JPanel
{
   public ImagePanel
   {
   }

    public void paintComponent(Graphics g)
    {
    }

}

Then add it to your normal class:

public class WardrobeFrame blah blah blah
{
    ImagePanel ip;

   public WardrobeFrame()
   {
      ip = new ImagePanel();
      add(ip, BorderLayout.CENTER);
   }
}

Something like that ;)

You may also want to use some nested JPanels in your program.

ok so I've made an ImagePanel class and put this code below to my WardrobeFrame now it looks like this:

public WardrobeFrame(Wardrobe wardrobe) {
		super("My Wardrobe");
		
		 ip = new ImagePanel();
	      add(ip, BorderLayout.CENTER);
	      
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		_wardrobeTableModel = new WardrobeTableModel(wardrobe);
		_wardrobeTable = new JTable(_wardrobeTableModel);
		
		Clock.getClock().addChangeListener(this);
		
		initGUI();
		pack();
		setLocationRelativeTo(null);
	}

and now its time for a stupid quesstion... how do I load an image? :)

I expected that question ;)

It's something like this:

INSIDE YOUR PAINTCOMPONENT METHOD:

g.drawImage(image, x, y, this);

or

g.drawImage(image, x, y, null);

I can't remember the last part, but I know it's one of the two.
