Hi, this is my first time posting so i hope this works correctly. I've been
googling for a while now,
and i'm trying to find a way to add a background image to this panel I made.
I was able to do it by adding a button:

======================================================
//panel class

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class instructionsPanel extends JPanel implements ActionListener
{
    background b1;

public instructionsPanel()
{

    b1 = new background();
    b1.setBounds(0, 0, 800, 500);
    add(b1);
    b1.addBackground();

    setLayout(null);
    setSize(800, 600);
    setBackground(Color.black);

    and so on....
}

//background class

import java.awt.*;
import javax.swing.*;

public class background extends JButton
{
    public background()
    {
        super();
    }

    String addBackground()
    {
        ImageIcon image1 = new ImageIcon("instructions.jpg");
        setIcon(image1);
        return "";
    }

}
======================================================

but i really don't like how the button's border flashes when the mouse
hovers
over it so i was wondering if anyone could help me with the code to just add
an
image to the background of the panel? Thanks for your time

import java.awt.*;
import java.awt.image.*;
import java.io.*;

import javax.imageio.*;
import javax.swing.*;

public class JImagePanel extends JPanel {
     private BufferedImage image;
     private boolean scale;

     public JImagePanel(String fname) throws IOException {
         image = ImageIO.read(new File(fname));
         setPreferredSize(new
Dimension(image.getWidth(),image.getHeight()));
     }

     public JImagePanel(BufferedImage image) {
         this.image = image;
         setPreferredSize(new
Dimension(image.getWidth(),image.getHeight()));
     }

     public JImagePanel(BufferedImage image, int width, int height) {
         this.image = image;
         setPreferredSize(new Dimension(width,height));
     }

     public JImagePanel(BufferedImage image, int width, int height,
      boolean scale) {
         this(image,width,height);
         this.scale = scale;
     }

     public void setImage(BufferedImage image) {
         this.image = image;
         repaint();
     }

     public void paintComponent(Graphics g) {
         if (scale)
             g.drawImage(image,0,0,getWidth(),getHeight(),this);
         else
             g.drawImage(image,0,0,this);
     }
}
