How to attach multiple inline base64 encode image to the mail?

Question

I have the following code

final JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper;
    try { 
      helper = new MimeMessageHelper(mimeMessage, false, "utf-8");
      String htmlMsg = "<body><div style="padding-top: 1px"><table 
       style="width: 100%">  <tr> <td align="left"><img align="left" 
       src="cid:**image1**" style="margin-left: -7px; width: 50%;"></td>                                    
       <td align="right"><img align="right" src="cid:**image2**"                    
      style="margin-left: 100px; width: 50%;"> </td>   </tr> </table></div> 
       <body>"



        Multipart multipart = new MimeMultipart("related");
        MimeBodyPart messageBodyPart = new MimeBodyPart();
        messageBodyPart.setContent(htmlMsg, "text/html");
        messageBodyPart.setDisposition(BodyPart.INLINE);
        multipart.addBodyPart(messageBodyPart);
        InternetHeaders headers = new InternetHeaders();
        headers.addHeader("Content-Type", "image/png");
        headers.addHeader("Content-Transfer-Encoding", "base64");
        String base64EncodedImageContentByteArray="encdoe value";
        String base64EncodedImageContentByteArray1 = "encoded value";
        MimeBodyPart imagePart1 = new MimeBodyPart(headers, 
        base64EncodedImageContentByteArray.getBytes());
        imagePart1.setDisposition(MimeBodyPart.INLINE);
        imagePart1.setContentID("image1");
        imagePart1.setFileName("image1.jpg");
        MimeBodyPart imagePart2 = new MimeBodyPart(headers, 
        base64EncodedImageContentByteArray1.getBytes());
        imagePart2.setDisposition(MimeBodyPart.INLINE);
        imagePart2.setContentID("image2");
        imagePart2.setFileName("image2.jpg");
        multipart.addBodyPart(imagePart1);
        multipart.addBodyPart(imagePart2);
        multipart.addBodyPart(messageBodyPart);
        mimeMessage.setContent(multipart);
        mimeMessage.setHeader("MIME-Version", "1.0");

But when I received the mail the first image is not showing but the second image showing in the mail. For first image place it is showing cross. Also I need to attache multiple images(base64 encoded value) in the mail

You should not encode in base64 yourself, you should leave that to JavaMail, and otherwise, look at this answer for inspiration: https://stackoverflow.com/a/28992525/466862 — Mark Rotteveel, Aug 20 '18 at 15:57
OK. But how to send multiple images, as my image is stored in DB as CLOB. — Subhajit Pal, Aug 20 '18 at 15:59
I used a comment, as it was a suggestion not directly related to your problem (although it could be). I would need to test this to find out what a solution would be as I don't normally work with inline images, and I don't have the time for that. I do see a lot of odd things in your code though (using the same `InternetHeaders` instance for both attachments, adding `messageBodyPart` twice, setting disposition inline for the message body, explicitly setting the mime version, your odd explicitly forcing base64, etc). They could all contribute to your problem (or maybe not ...). — Mark Rotteveel, Aug 20 '18 at 16:10
Yes, there's a lot of extraneous operations in your code. This [JavaMail FAQ entry](https://javaee.github.io/javamail/FAQ#sendmpr) should help you simplify things. — Bill Shannon, Aug 20 '18 at 19:02
