Embedded Images and MAPI?

Is there some way to send emails with embedded images via standard MAPI?
That is, images that will be displayed inline by the recipient's email
client?

I need an approach that will work with any standard-MAPI-compliant email
client on the sender's system, not just Outlook.

Do I start by MIME-encoding the image, then putting that in the MAPI
message body? Is it best to wrap this in HTML?

Your tips greatly appreciated.
