BAckground image in JFrame?

[Krocker]

hiya guys, ok so i was wondering is there a way of adding a background image into my program. I have a gif image in the same folder as my program, and i have tried a lot of different things, but for some reason, when i compile, nothing shows up just my program with a blank/original background. Im also having trouble moving the buttons around, they dont seem to want to move. Heres the codes for my program if you need them:

code:

package kcleaner; import java.awt.Graphics; import java.awt.Image; import java.awt.MediaTracker; import java.awt.Toolkit; import javax.swing.JPanel; import java.awt.BorderLayout; import java.awt.Container; import javax.swing.BorderFactory; import javax.swing.JFrame; import javax.swing.border.Border; import java.awt.event.*; import javax.swing.*; import java.io.*; import java.awt.*; public class KCleaner extends JFrame implements ActionListener {     public JFrame f1 = new JFrame (" K  C l e a n e r");     public JPanel p1 = new JPanel ();     public JButton b1 = new JButton ("Clean");     public JButton b2 = new JButton ("ABOUT");     public Container pane;     public Image im = Toolkit.getDefaultToolkit ().getImage ("kcleaner/Icon.gif");     // public Image bg = Toolkit.getDefaultToolkit ().getImage ("kcleaner/Background.gif");     ImageIcon bg = new ImageIcon ("kcleaner/Background.gif");     public JLabel bgpic = new JLabel (bg);     public KCleaner ()     {         f1.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);         f1.setIconImage (im);         b1.addActionListener (this);         b2.addActionListener (this);         f1.setContentPane (p1);         f1.setSize (400, 400);         p1.add (b1);         p1.add (b2);         p1.add (bgpic);         f1.setVisible (true);     }     public void actionPerformed (ActionEvent e)     {         dProcess method = new dProcess ();         if (e.getSource () == b1)         {             String drive = JOptionPane.showInputDialog (null, "Please Enter Your Main Hard Drive Letter", "Hardrive", JOptionPane.QUESTION_MESSAGE);             // String user = JOptionPane.showInputDialog(null, "Please Enter The User Accout Name", "User Account", JOptionPane.QUESTION_MESSAGE );             String folder = drive.toUpperCase () + ":\\Nexon/Combat Arms/BlackCipher";             int value = 25;             // int i;             if (folder == null)             {                 JOptionPane.showMessageDialog (null, "Directory does not exist.");             }             else             {                 JOptionPane.showMessageDialog (null, "KCleaner is Done!");                 method.directory (new File (folder));             }         }         else if (e.getSource () == b2)         {             JOptionPane.showMessageDialog (null, "KCLEANER  V1.0  by Krocker");         }     }     public static void main (String[] args)     {         new KCleaner ();     } }
