Using multipart mime type gets around that handily with "embedded" 
images.  In a nutshell, instead of having <img 
src="http://example.com/images/widget.jpg" ...> you include the image as 
an attachment, and have something like <img src="cid:my-attach-52454"> 
where 'my-attach-52454' is the Content-ID of the attached binary file. 
The email message as a whole has a content type of multipart/related.

That's a problem that comes from poor HTML email formatting.  Kinda like 
some websites look on a PDA or webphone.

Is the email client in question Thunderbird?  TB wisely blocks images in 
HTML messages that are loaded from a remote location, but will display 
messages with embedded HTML images.

Prolly I'm gonna get flamed on the basis of bandwidth consumption or 
something.  No defense on that count!  As always, it is best to Know 
Thine Audience.
