1526710 - image in HTML email is not shown in the body

Status: RESOLVED DUPLICATE of bug 61815

(MailNews Core :: MIME, defect)

Description

[:aceman]

Attachment: img-in-sig.eml

There are cases when there is an <img> tag inside a HTML email message, the image is not shown inline in the proper place in the HTML document, but as an attachment (shown inline below the message body, if the proper pref is true).

Attached is a sample sanitized message. It seems to be created in Outlook for Mac. Is there any problem in the MIME encoding of the message, or is it a TB bug?

Most of these bugs are invalid or a duplicate of something we already have on file.

This bug here is invalid. Let's look at the MIME structure:

multipart/mixed
multipart/alternative
text/plain
text/hmtl (foolishly referencing the image which is an attachment)
image

So the image is clearly an attachment in a multipart/mixed structure.

Anyway, this case was discussed in bug 61815 from the year 2000. Nice the M$ haven't learned how to produce proper MIME compliant messages in almost 20 years :-(

I can't say I like markdown :-( - Here the thing again:

multipart/mixed
  multipart/alternative
    text/plain
    text/hmtl (foolishly referencing the image which is an attachment)
  image

For embedded images multipart/related is needed.
