    For displaying image(s) make a JPanel extension and override the
    paintComponent(Graphics g) -method, load the image first and draw it in this method. The selection of a region should be done by detecting mouseclicking/dragging via a MouseListener and a MouseMotionListener. If a simple rectangular selection is not enough you should look into the classes that extend the Shape -interface.

    For selecting a region of a displayed image use java.awt.CropImageFilter.
    eschew obfuscation
