HTML Email in Gmail - embedding images
HTML mail with an embedded image in gmail - with the following email body - just spits out the exact text. It does not show what's inside the "body" tags.
This is the content of the mail:
Content-Type: multipart/related;
boundary="bananarepublic12345"
This is a multipart message in MIME format.
--banana12345republic
Content-Type: text/html; charset=ISO-8859-1
Content-Transfer-Encoding: 7bit
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"

Where am I going wrong?
Thanks for any suggestion!
I've followed the instructions in question 4018709 and it worked nicely. To sum it up, you need the content-ids for the attachment to be formatted like message IDs (which in turn are formatted like email addresses - with an @ and a domain), and have the content ID value in the MIME part header of the image enclosed in angle brackets (like you already do).
So a sample email may look like this:
Date: Fri, 2 Dec 2011 06:57:55 GMT
Message-Id: <201112020657.pB26vttQ010231@geek.co.il>
Content-Type: multipart/related; boundary="=-blabla"; type="multipart/alternative"
From: Some sender <some-sender@geek.co.il>
To: Me <me@geek.co.il>
Subject: HTML content with embedded images
MIME-Version: 1.0
--=-blabla
Content-Type: text/html; charset="utf-8"
Content-Transfer-Encoding: quoted-printable
<html><body>
