I guess Dani means something else:
http://www.systemnetmail.com/faq/4.4.aspx
This method allows to refer to an inline attachment using <img
src="cid:image_content_id"/>.
This is the only way to be sure the recipient actually sees the image
as most MUAs don't display images from external URLs. Also, many MUAs
and MTAs flag such emails as spam (and they have good reasons to do
so).
