Menu
Position your cursor where you want the image in your message. In the ribbon, select Insert > Pictures. Browse your computer or online file locations for the picture you want to insert. Select the picture, then select Insert.
The HTML <img> tag is used to embed an image in a web page. Images are not technically inserted into a web page; images are linked to web pages. The <img> tag creates a holding space for the referenced image. The <img> tag is empty, it contains attributes only, and does not have a closing tag.
Try to insert it directly, this way you can insert multiple images at various locations in the email.
<img src="data:image/jpg;base64,{{base64-data-string here}}" />
And to make this post usefully for others to: If you don't have a base64-data string, create one easily at: http://www.motobit.com/util/base64-decoder-encoder.asp from a image file.
Email source code looks something like this, but i really cant tell you what that boundary thing is for:
To: [email protected]
Subject: ...
Content-Type: multipart/related;
boundary="------------090303020209010600070908"
This is a multi-part message in MIME format.

//EDIT: Oh, i just realize if you insert the first code snippet from my post to write an email with thunderbird, thunderbird automatically changes the html code to look pretty much the same as the second code in my post.
The other solution is attaching the image as attachment and then referencing it html code using cid.
HTML Code:
<html>
<head>
</head>
<body>
<img width=100 height=100 id="1" src="cid:Logo.jpg">
</body>
</html>
C# Code:
EmailMessage email = new EmailMessage(service);
email.Subject = "Email with Image";
email.Body = new MessageBody(BodyType.HTML, html);
email.ToRecipients.Add("[email protected]");
string file = @"C:\Users\acv\Pictures\Logo.jpg";
email.Attachments.AddFileAttachment("Logo.jpg", file);
email.Attachments[0].IsInline = true;
email.Attachments[0].ContentId = "Logo.jpg";
email.SendAndSaveCopy();
I don't find any of the answers here useful, so I am providing my solution.
The problem is that you are using multipart/related as the content type which is not good in this case. I am using multipart/mixed and inside it multipart/alternative (it works on most clients).
The message structure should be as follows:
[Headers]
Content-type:multipart/mixed; boundary="boundary1"
--boundary1
Content-type:multipart/alternative; boundary="boundary2"
--boundary2
Content-Type: text/html; charset=ISO-8859-15
Content-Transfer-Encoding: 7bit
[HTML code with a href="cid:..."]
--boundary2
Content-Type: image/png;
name="moz-screenshot.png"
Content-Transfer-Encoding: base64
Content-ID: <part1.06090408.01060107>
Content-Disposition: inline; filename="moz-screenshot.png"
[base64 image data here]
--boundary2--
--boundary1--
Then it will work
If it does not work, you may try one of these tools that convert the image to an HTML table (beware the size of your image though):
Using Base64 to embed images in html is awesome. Nonetheless, please notice that base64 strings can make your email size big.
Therefore,
1) If you have many images, uploading your images to a server and loading those images from the server can make your email size smaller. (You can get a lot of free services via Google)
2) If there are just a few images in your mail, using base64 strings is definitely an awesome option.
Besides the choices provided by existing answers, you can also use a command to generate a base64 string on linux:
base64 test.jpg
I know this is an old post, but the current answers dont address the fact that outlook and many other email providers dont support inline images or CID images. The most effective way to place images in emails is to host it online and place a link to it in the email. For small email lists a public dropbox works fine. This also keeps the email size down.
