Embed image in html email using system.net.sendEmail

Is it possible to send an email using system.net.sendEmail that will be HTML and have the attached image embedded in the body of the email? If so does someone have an example? I see in the documentation there was some support for MIME, but the examples do not go into detail about how it works or how to use it.

I would be surprised if you can get this to work within the boundaries of our scripting functions, but it would probably be possible to write a script to run on the gateway that accesses the underlying Java mail APIs and does this for you.

Well, I did have it working 7.9 using smtplib and email, but for some reason in 8.1 when I go to use smtp sendmail and the file is over 56 kb it times out. still works perfectly fine in 7.9 against the same email server. I was hoping there was native support for embedded images.

I tried importing javax.mail but is says there is no module named mail. I am on 8.1.32

Just caught that you said on the gateway. I just tried importing javax.mail from with the gateway scope and that works. I will give that a try.
