Rainer,

one approach could be to allow latex to create the PDF and the convert
(using the shell, say) the PDF to a PNG and include that:

--8<---------------cut here---------------start------------->8---
#+begin_src latex :file fsa.pdf :packages '(("" "tikz"))

[...]

#+end_src
#+begin_src sh
  convert -density 300 fsa.pdf fsa.png
#+end_src

#+attr_html: width=50%
  [[file:./fsa.png]]
--8<---------------cut here---------------end--------------->8---

This works.  However, my babel knowledge is not up to speed so I don't
know how to tell it to not output anything in the HTML document for
the two babel snippets (latex and sh).  If you know how, let me know!

HTH,
eric
