Adding a graphic to e-mail body

I am using a TIdSMTP to mail out reports twice daily. Got everything working
perfect.  Now I am getting greedy and am trying to add our company logo to
the bottom of the E-mail body.

I assume is is something along the lines of
Body.AddObject('',MyImage) but of course, there is more to it.
Do I add the image to an image component and cast the image to TObject or
create a handle to the image and cast that?

Could use a little guidance.

Thanks
