Apparently, you do not yet fully understand HTML and ZPT.

HTML (and therefore ZPT) is *NOT* intended to present
binary data (such as images).

I expect you do not understand "MIMEImage" as well.
I do not know what it is for but almost surely, it is not
for presentation via HTTP...

And it would not work. "dtml-mime" is for construction of an "email" message
from DTML and not for a webpage presentation.


Step back. Read a good book about Web publishing, HTML and HTTP.
Learn about how to present binary information in web pages
(i.e. via HTTP) -- you will need the "Content-Type" header
of HTTP responses.
Read about Zope's "REQUEST" and "RESPONSE" objects (in the Zope book or

  <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>)


You will *not* need a ZPT (nor DTML) for presentation
of binary content. You use then only for textual content.
