Embedding images in Org Mode for HTML export

I've got this code:

#+begin_src latex :packages '(("" "tikz")) :exports results :results output
raw :file fsa.png
\usetikzlibrary{backgrounds}
\begin{tikzpicture}
  \draw (0,0) grid (10,5);
  \draw (0,0) node[below left] {$A$};
  \draw (10,5) node[above right] {$B$};
  \fill (0,0) circle (2pt);
  \fill (10,5) circle (2pt);
\end{tikzpicture}
#+end_src

#+begin_src latex :packages '(("" "qtree")) :exports results :results
output raw :file tree1.png
 \Tree [.sum [.squares [.prime-numbers initial seven ] ] ]
#+end_src

running in an org file, and it gives me embedded images in an html file.
(See this <http://147pm.info/omtest1.html>). But they're cramped and have a
strange gray background. How can I not clip and get the png transparent
working?

I added these options to the src block

 :imagemagick yes :iminoptions -density 600 :imoutoptions -geometry 800

and the first src block works for me: images are proper size and the
background is transparent.  I could not test the second as I don't have
qtree.

The process might depend on what your system uses to generate the images
from LaTeX.

That seemed to work -- sometimes. But it's probably best to simply produce
each graphic separately, then embed as a png in the org file.
