title: how to add Image in JPanel
body: <p>I add a tabbedpane in my frame and call tab.add(" ",new Img()) that extends Img with JPanel ..</p>
  
  <p>The question is: Could I add JScrollPane in that JPanel and drawImage as JPanel's background and also to do additional drawing on that image such as making route on background image(such as map) because I want to apply Prim's algorithm on those route...</p>
  
  <p>And also if I wish to add additional panel on tabbedpane like above, how could I control those tab actions..</p>
  
  <p>The sample code is like that...</p>
  
  <p>If you have any idea on Prim's algorithm and graph algorithm please help me!
  Thanks!</p>
