Problem in embedding Multiple Images

Question

Dear members,
I am composing a mail in java mail. In the body i am trying to embed (Note: Not attach) three images files. But, only the first image is getting embedded. Other 2 images are only getting attached, not coming as embedded images.I tried various options like changing Mime subtype, setting disposition as inline, etc... But nothing worked. I am pasting the code here. Any help is high appreciated.
MimeMultipart multiPart = new MimeMultipart("alternative");
File folder = new File("./result");
File[] listOfFiles = folder.listFiles();
for (int i = 0; i < listOfFiles.length; i++)
System.out.println("Attaching file " + listOfFiles.getAbsolutePath());
MimeBodyPart msgBody = new MimeBodyPart();
String htmlText = "<img src=\"cid:image"+i+"\">";
msgBody.setContent(htmlText, "text/html");
mp.addBodyPart(msgBody);
MimeBodyPart attachmentPart = new MimeBodyPart();
FileDataSource fds = new FileDataSource(listOfFiles[i].getAbsolutePath());
attachmentPart.setDataHandler(new DataHandler(fds));
attachmentPart.setFileName(listOfFiles[i].getName());
attachmentPart.setHeader("Content-Type", "image/png" );
attachmentPart.setHeader("Content-ID","image"+i);
mp.addBodyPart(attachmentPart);
Thanks

Sorry for the delay in my response. I was on vacation.
I tried following code (giving the type as related). But still it didn't work out :(
I am sure i am doing some silly mistake. I guess mistake is in how i use cid:imageDo i need to use four unique cid tag if i attach four images? If yes can someone help me how? Thanks
MimeMultipart multiPart = new MimeMultipart("related");
MimeBodyPart msgBody = new MimeBodyPart();
String htmlText = content+"<H1></H1><img src=\"cid:image\">";
msgBody.setContent(htmlText, "text/html");
multiPart.addBodyPart(msgBody);
File folder = new File("./result");
File[] listOfFiles = folder.listFiles();
for (int i = 0; i < listOfFiles.length; i++)
MimeBodyPart attachmentPart = new MimeBodyPart();
FileDataSource fds = new FileDataSource(listOfFiles.getAbsolutePath());
attachmentPart.setDataHandler(new DataHandler(fds));
attachmentPart.setFileName(listOfFiles[i].getName());
attachmentPart.setHeader("Content-Type", "image/png" );
//attachmentPart.setDisposition("inline");
attachmentPart.setHeader("Content-ID","image"+i);
mp.addBodyPart(attachmentPart);
System.out.println("Attached the file " + listOfFiles[i].getAbsolutePath());
mess.setContent(multiPart);
