Mimemail: How to send image "inline"?

Hello,

I sent html-mails via Mimemail and I want to include an image as attachment.

At the moment I include the image as <img src="path-to-online-image"> in mimemail-message.tpl.php.

The Mails are sometimes classified as “Spam” and I think one reason could be the external loading of the image.

How can I include the image as “attachment” and link that image in mimemail-message.tpl.php?
