HTML.
The custom is to post in plain text, but I tried once to send an html
post on a private nntp server as a test and it certainly worked (1).
There were no filters to block it. Some people scandalized, so I did not
repeat the experiment, but it showed that the technology was in place,
just unused.
I am this moment subscribing to
rec.arts.tv to see that post in
Thunderbird. I use leafnode as proxy.

Yes, the photos do show. Not by default, Thunderbird warns that there is
remote content, and I have to explicitly enable it - same as for any
html email I get. That is, the post doesn't include the photos, they are
downloaded when you open the post.
You can probably view the source at your side.
(1) that nntp server had a gateway to a web forum, and they of course
posted with text format and sometimes photos, and they were lost when
gated to the nntp side. So I tried to see if nntp was html capable, and
it was. It was just the gateway that wasn't.
