Hi experts,
                i was trying out a program on sending a mail using Javamail. The contents of the mail would be just an embedded image (not an attachment). I was able a similar mail. Gmail seems to work, but if the same mail is sent to an id which is viewed through outlook express (2003) my image is lost. Attaching the code below. The contents of the html file i am using is as below :
 <BODY>
  <img src="cid:image">
 </BODY>

Please let me know what i am supposed to add..
package org.me.mail.Test;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.*;
import javax.mail.internet.*;
 
import java.io.File;
import java.util.*;
 
public class MailOnGmailnSSL
{
  String  d_email = "xxxxx@gmail.com",
          d_password = "xxxx",
          d_host = "smtp.gmail.com",
          d_port  = "465",
          m_to = "xxxx@companyName.com",
          m_subject = "Testing",
          m_text = "Hey, this is the test mail.";
  
  public static final String TXT_FILE = "c:\\temp\\text_contents.txt";
  public static final String HTML_FILE = "c:\\temp\\html_contents.html";
  public static final String IMAGE_FILE = "c:\\temp\\ch851118.gif";
  
  public MailOnGmailnSSL()
  {
      Properties props = new Properties();
      props.setProperty("proxySet","true");
      props.setProperty("socksProxyHost","proxy.sgp.hp.com");
      props.setProperty("socksProxyPort","8080");
      props.put("mail.smtp.user", d_email);
      props.put("mail.smtp.host", d_host);
      props.put("mail.smtp.port", d_port);
      props.put("mail.smtp.starttls.enable","true");
      props.put("mail.smtp.auth", "true");
      //props.put("mail.smtp.debug", "true");
      props.put("mail.smtp.socketFactory.port", d_port);
      props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
      props.put("mail.smtp.socketFactory.fallback", "false");
      
 
      SecurityManager security = System.getSecurityManager();
 
      try
      {
          Authenticator auth = new SMTPAuthenticator();
          Session session = Session.getInstance(props, auth);
          session.setDebug(true);
 
          MimeMessage msg = new MimeMessage(session);
          Multipart mp = new MimeMultipart("alternative");
          BodyPart bp = getFileBodyPart(TXT_FILE);
          mp.addBodyPart(bp);
          
          
          //msg.setText(m_text);
          msg.setSubject(m_subject);
          msg.setFrom(new InternetAddress(d_email));
          msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
          
          Multipart mp_html = new MimeMultipart("related");
          BodyPart bp_html = getFileBodyPart(HTML_FILE);
          mp_html.addBodyPart(bp_html);
          
          String cid = "cid:image";

          bp2.setContent(mp_html);
          
          mp.addBodyPart(bp2);
          
          msg.setContent(mp);
          
          Transport.send(msg);
      }
      catch (Exception mex)
      {

Are you sure it's not just the Outlook config? What happens when you send an embedded image with another app to that Outlook?

I'm asking: what happens if you send an embedded image to the same instance of Outlook from another program?

oh.. that works.. Correct me if i am wrong but an embedded image is just an image being pasted onto the mail window (in html format) and on receiving it comes inline with the mail and not as an attachment rt .. If thts the case, it works when i sent it from gmail..

An embedded image is just a multipart with an inline html image reference to the image content

Check out

http://java.sun.com/developer/onlineTraining/JavaMail/exercises/MailHtml/

I think you'll find it's Content-ID you need (note hyphen, not underscore). Check out the html source of the one that *does* work in Outlook
