How can I create an HTML message which will contain multiple images?

Extending the single image FAQ to multiple images works fine. The extra images should not be treated as attachments, vs. inline images:

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

public class HtmlImageExample {
  public static void main (String args[]) throws Exception {
    String host = args[0];
    String from = args[1];
    String to = args[2];
    String file = args[3];
    String file2 = args[4];

    // Get system properties
    Properties props = System.getProperties();

    // Setup mail server
    props.put("mail.smtp.host", host);

    // Get session
    Session session = Session.getDefaultInstance(props, null);

    // Create the message
    Message message = new MimeMessage(session);

    // Fill its headers
    message.setSubject("Embedded Image");
    message.setFrom(new InternetAddress(from));
    message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

    // Create your new message part
    BodyPart messageBodyPart = new MimeBodyPart();
    String htmlText = "<H1>Hello</H1>" + 
      "<img src="cid:memememe"><p>"  +
      "<img src="cid:youyouyou">";
    messageBodyPart.setContent(htmlText, "text/html");

    // Create a related multi-part to combine the parts
    MimeMultipart multipart = new MimeMultipart("related");
    multipart.addBodyPart(messageBodyPart);

    // Create part for the image
    messageBodyPart = new MimeBodyPart();

    // Fetch the image and associate to part
    DataSource fds = new FileDataSource(file);
    messageBodyPart.setDataHandler(new DataHandler(fds));
    messageBodyPart.setHeader("Content-ID","<memememe>");

    // Add part to multi-part
    multipart.addBodyPart(messageBodyPart);

    // Create 2nd part for the image
    messageBodyPart = new MimeBodyPart();

    // Fetch the image and associate to part
    DataSource fds2 = new FileDataSource(file2);
    messageBodyPart.setDataHandler(new DataHandler(fds2));
    messageBodyPart.setHeader("Content-ID","<youyouyou>");

    // Add part to multi-part
    multipart.addBodyPart(messageBodyPart);

    // Associate multi-part with message
    message.setContent(multipart);

    // Send message
    Transport.send(message);
  }
}
