I you would read my <http://www.rossde.com/internet/ASCIIvsHTML.html>,
which I cited earlier in this thread, you would see under "Methodology"
the following:
"I excluded any attachments (which, for HTML-formatted messages, means
excluding any images or background), links to attachments, the section
for marking a message as spam (added by my ISP's mail server), and the
header section of each message."

The sizes from which I computed bloat DID NOT INCLUDE IMAGES.  For the
actual HTML-formatted messages, I copied the message source from just
after the <x-html> tag to just before the </x-html> tag and pasted the
result into a new file; I then considered the size of the resulting
file.  For the equivalent ASCII-formatted messages, I copied the body of
a displayed HTML-formatted message from my E-mail client and pasted the
result into a new file; I then considered the size of the resulting
file.  The sizes for each of the 20 messages -- both HTML and ASCII --
are shown in a table at the end of my cited Web page.

You might think that images in an HTML-formatted message traverse the
Internet embedded within the message.  Actually, images travel
separately, as attachments.  Similarly, there is a separate transfer of
a file for each image in a Web page.
