Is there any way to actually embed (not link to) an image in an email template in salesforce? What I have in mind would create an email with a 'Content-Type: text/html; charset="us-ascii"' in which it would refer to images like this:
<img src="cid:image001.png@01CD11BA.4FD2D9A0" ....
so that the images are in the email, not gotten from a webserver.
I haven't seen any way to do this, everything refers to hosting them at salesforce in the documents (I would do that on my own webserver instead then).
