[O] Export tikz Figures Issue

[Aric]

I apologize for the sudden flurry of postings, but I am finding some great 
solutions within Org. 

I have very happily managed to find the more recent references to babel 
latex and tikz figures with the imagemagick conversion, and this works 
absolutely beautifully within the Org mode buffer. 

I have not been successful in exporting the image (html or odt) however. I 
can export it if I create a link to the generated png image, rather than 
leaving it to the results section like I can with latex. Here is an example:

Working R:

#+name: fig:bplotil8staph
#+headers: :results graphics :file /somewhereelse/bplotil8staph.png
#+begin_src R 
bwplot(il.8 ~ impression,....)
#+end_src

#+CAPTION: Plot demonstrating significantly increased IL-8 levels during /S. 
aureus/ pneumonia as compared to colonization. 
#+RESULTS: bplotil8staph
[[file:/somewhereelse/bplotil8staph.png]]

Note that this link is generated by the R output and I can see the image 
along with the caption in both Org buffer and exported files. 

Not working so well LaTeX:

#+name: fig:markovdesc
#+headers: :imagemagick yes :iminoptions -density 600 :imoutoptions -
geometry 800 
#+headers: :file /somewhereelse/plot_markovModel.png :fit yes
#+begin_src latex  :buffer no :packages '(("" "tikz")) 
\usetikzlibrary{shadows,arrows,automata,decorations.text,shapes,snakes,fit}
\tikzstyle{ball} = [circle,shading=ball,minimum size=1cm] 
\begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=4.2cm]
  \tikzstyle{everystate}=[draw=black,thick,scale=1,align=center]
  \node [state,initial,text width=4em,align=center,ball,text=black,ball 
color=green!70!black,drop shadow] (A)                {{\small Post-
Transplant State 1}};
  \node [state,align=center,text width=4em,ball,text=black,ball 
color=purple!70,drop shadow]              (B)  [right of=A]  {{\small BOS 
~~~State 2}};
    \path (A) edge [bend left] node[above]   {{\small $\lambda_{12}(t)$ 
Covariates~$HR_{12}$}} (B);
  \node[state,align=center,text width=4em,ball,text=black,ball 
color=blue!50,drop shadow]                (C)  [below=2.6cm,right=1cm] 
{{\small Death ~~~State 3}};
    \path (A) edge [] node[left] {{\small $\lambda_{13}(t)$ 
Covariates~$HR_{13}$}} (C);
    \path (B) edge [] node[right] {{\small $\lambda_{23}(t)$ 
Covariates~$HR_{23}$}} (C);
\end{tikzpicture}
#+end_src

#+CAPTION: Basic idea of the model demonstrating the transition states. 
#+RESULTS: fig:markovdesc
#+BEGIN_LaTeX
[[file:/fitz/Rworkarea/gnr/new_work/staph/plot_markovModel.png]]
#+END_LaTeX

For the LaTeX there is no image in the exported buffers and the in-text link 
to the image is not active at all. Things only work for latex tikz in the 
Org buffer. 

What am I doing wrong? Or do I need to create a manual link to the file?

Thanks so much for suggestions.
