Jak zastosować obrazek.jpg jako tło projektu w NetBeans?

Tło projektu? O co chodzi? Konsola ma ci wyświetlać JPGa?

Na tle obrazek.jpg mają być kompomenty, a nie obok tła. Robie aplikacje w formie Java Desktop Application (FrameView).
Pytanie:
Jak wstawić tło do tego projektu, aby komponenty wrzucone do tej mojej formy były na tle obrazku.jpg, a nie obok.

Jeśli nie zależy Ci na korzystaniu z menadżeró rozkładu, to możesz zrobić tak:
setLayout(null);
setPreferredSize(new Dimension(750,406));
JButton b=new JButton("Abrakadabra");
b.setBounds(10,10,120,25);
b.addActionListener(this);
add(b);
b=new JButton("Hokus-pokus");
b.setBounds(10,110,120,25);
add(b);
JTextField tf=new JTextField(10);
tf.setBounds(10,210,120,25);
add(tf);
JLabel l=new JLabel("Abrakadabra");
l.setBounds(10,310,120,25);
add(l);
JLabel tlo=new JLabel(new ImageIcon("images/ayers.jpeg"));
tlo.setOpaque(true);
tlo.setBounds(0,0,750,406);
add(tlo);
JLabel z obrazkiem tła musi być ostatnim dodawanym elementem i musi być przezroczysta (setOpaque(true);).

a jakiś inny sposób?
