How to set a jpg image ContentType of JEditorPane

Question

Hi how can i display an image on a JEditorPane like image.jpg?
I tried myEditor.setContentType("image/jpeg") but it still displays characters instead of the image.
import java.awt.*;
import javax.swing.*;
import java.io.*;
public class Pagina extends JFrame implements Runnable {
     JEditorPane e;
     public Pagina(){
          super("fds");
          e = new JEditorPane();
          e.setEditable(false);
          e.setContentType("image/jpeg");
          Container c = getContentPane();
          c.add(e);
          setSize(400,400);
          setVisible(true);
          Thread t = new Thread(this);
          t.start();
     public void run(){
          while(true){
               try{
               e.setPage( "http://10.0.0.5/SnapShot.jpg" );
               Thread.sleep(1000);
          catch(IOException ioe){}
          catch(InterruptedException ie){}
     public static void main (String [] args) {
          new Pagina();
}

In your current app, you are trying to redisplay an image in some infinite loop. This smells bad to me. I am no expert in java graphics, far from it, but if you want to paint a background image within a JEditorPane, since JEditorPane is a component and has to paint itself, you could override its paintComponent method and draw an image inside there using the Graphics object.
another way is to put the JEditorPane on top of a JPanel that draws your picture. In both instances, I think that you'll need to set the JEditorPane's opaqueness to "false".
Something like so, perhaps?
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import javax.imageio.ImageIO;
import javax.swing.BorderFactory;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
class ImageJEditorPane extends JPanel
    private static final String IMAGE_FILE1 = "disc/d1/f/image1.jpg";   
    private static final String IMAGE_URL = "http://10.0.0.5/SnapShot.jpg";
    private BufferedImage myImage = null;
    private JEditorPane editorPane;
    ImageJEditorPane()
        try
            setPreferredSize(new Dimension(800, 650));
            setBorder(BorderFactory.createEmptyBorder(15, 15, 15, 15));
            setLayout(new BorderLayout());
            //myImage = ImageIO.read(new File(IMAGE_FILE1));
            myImage = ImageIO.read(new URL(IMAGE_URL));
            editorPane = new JEditorPane()
                @Override
                protected void paintComponent(Graphics g)
                    g.drawImage(myImage, 0, 0, null);
                    super.paintComponent(g);
            editorPane.setPreferredSize(new Dimension(1200, 1000));
            editorPane.setOpaque(false);
            JScrollPane scrollPane = new JScrollPane(editorPane);
            add(scrollPane, BorderLayout.CENTER);
        catch (IOException e)
            e.printStackTrace();
     //or you could do it this way
    protected void paintComponent(Graphics g)
        super.paintComponent(g);
        g.drawImage(myImage, 0, 0, null);
    private static void createAndShowGUI()
        JFrame frame = new JFrame("ImageJEditorPane Application");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(new ImageJEditorPane());
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    public static void main(String[] args)
        javax.swing.SwingUtilities.invokeLater(new Runnable()
            public void run()
                createAndShowGUI();
