It wouldn't make much sense for him to have supplied a working example, would it?  :-) :-)

Anyway, if you were to try view the mail in T-Bird you'd find it to be as originally described. 

I had a bit more time to look at this in the evening and I can see what is being "expected" of T-Bird.  If you look at the MIME headers for the images you'd these headers as an example....

Content-Type: image/jpeg
Content-Transfer-Encoding: base64
Content-Disposition: inline
Content-ID: <tAhk9iyMmm1CIfpU4g9p>

The "key" being the Content-ID. 

Then, in the text/html section of the message you'd find this sort of html snippet....

            <div class=3D"yiv3030508851ecxyiv7863957078MsoNormal" style=3D"=
BACKGROUND:white;"><span style=3D"FONT-SIZE:16pt;FONT-FAMILY:Arial, sans-se=
rif;COLOR:black;"><img id=3D"yiv3030508851ecxyiv7863957078_x0000_i1044" alt=
=3D"[]" src=3D"cid:tAhk9iyMmm1CIfpU4g9p" width=3D"561" height=3D"405" data-=
id=3D"17bfaf0f-58fa-c795-9880-bde833a43cb7"></span>

Notice the cid:tAhk9iyMmm1CIfpU4g9p?  Which is referring to image via the "Content-ID"?  I don't know what standard defines this, but it seems clear that the HTML engine of T-Bird can't handle this.
