Java: adding Image to JTable?

I have a big button when clicked , adds an image to a table

    class BigButtonListener implements ActionListener{
 Image screenshot=null;
 Browser bigbrowser =null;

 BigButtonListener(Browser browser, DefaultTableModel dataModel, DefaultTableModel historyModel, JTable dataTable, JTable historyTable) {
  screenshot = browser.toImage(true);
  bigbrowser = browser;
  historyTable = historyTable;
  //table1.addRow
 }

  @Override
  public void actionPerformed(ActionEvent e) {
   // save current image
   historyModel.insertRow(0,new Object[]{new ImageIcon(screenshot)}); 
   //System.out.println(historyTable.getRowCount());

  }   
}

however, all this adds is the text javax.swing.ImageIcon@9dfb04 and not the actual picture.

DefaultTableCellRenderer extends JLabel and renders by simply setText(value.toString()).

Follow the definite Swing tutorial on custom cell renderer and editor.

Or use simple hack like this:

historyTable.setDefaultRenderer(Object.class, new DefaultTableCellRenderer() {
    protected void setValue(Object value) {
        if( value instanceof ImageIcon ) {
            setIcon((ImageIcon)value);
            setText("");
        } else {
            setIcon(null);
            super.setValue(value);
        }
    }
});
