How do I remove a line around a label image. I set the background and foreground color to the panel color and put a check in the property opaque checkbox.

Thank you,

We need to see some code.  I don't see the problem you describe in the 
code below.  Are you using AWT?

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

public class test2 extends JPanel {
     private JLabel l;

     public test2() {
         super(new GridBagLayout());

         GridBagConstraints c = new GridBagConstraints();

         setPreferredSize(new Dimension(240,180));
         try {
             // use blue.png if you want to see the image
             URL url = new URL("http://knutejohnson.com/white.png");
             ImageIcon icon = new ImageIcon(url);
             l = new JLabel(icon);
         } catch (MalformedURLException murle) {
             murle.printStackTrace();
         }

         add(l,c);
     }

     public static void main(String[] args) {
         EventQueue.invokeLater(new Runnable() {
             public void run() {
                 JFrame f = new JFrame("test2");
                 f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                 test2 t2 = new test2();
                 f.add(t2,BorderLayout.CENTER);
                 f.pack();
                 f.setVisible(true);
             }
         });
     }
}

I'm not seeing any line around the image or the JLabel.  A screen shot 
from my Windows XP with Java 7 computer here: 
http://http://knutejohnson.com/line.png.  What is your configuration?

Your code would be a boat load more readable with some imports.

     Ran your code on my system: No tiny line.  I'll repeat an
earlier question: Are you sure this mysterious line isn't part
of the image you're displaying?

I think the line is indeed part of the image! It's an image just like the dancing baby image.

Again I'm not seeing any lines but I don't have the image.  Post the 
image some place.

What OS are you using?  What Java version?

Also, the code to set the look and feel must be run on the EDT.  Just 
put that code inside the EventQueue.invokeLater run method.

One other thing to consider is that look and feel must be changed from 
the EDT although I don't think that would cause this problem.

If you're sure the line is not part of the image itself (a border,
perhaps), please post an SSSCE.  This works fine for me:


     import javax.swing.ImageIcon;
     import javax.swing.JFrame;
     import javax.swing.JLabel;
     import javax.swing.SwingUtilities;
     public class Foo {
        public static void main(String[] unused) {
           SwingUtilities.invokeLater(new Runnable(){
              @Override
              public void run() {
                 JFrame frame = new JFrame("Foo");
                 frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                 ImageIcon icon = new ImageIcon("icon.jpg");
                 frame.add(new JLabel(icon));
                 frame.pack();
                 frame.setVisible(true);
              }
           });
        }
     }
