How to generate the following latex fragment through org-mode "#+ATTR_LATEX:" or others:

\begin{figure}[!htbp]
  \centering
  \begin{minipage}[b]{0.6\textwidth}
    \captionstyle{\centering}
    \centering
    \includegraphics[width=4cm]{fig/test1.png}
    \bicaption[fig1]{Where}{Fig}{there is a way.}
  \end{minipage}     
\end{figure}

I have done partially of it by using:

#+ATTR_LATEX: :caption \bicaption[fig1]{Where}{Fig}{there is a way.} :width 10cm
[[file:fig/test1.png]]

However the following no work:

#+ATTR_LATEX: :environment minipage :option [b]{0.6\textwidth} :caption \bicaption[fig1]{Where}{Fig}{there is a way.} :width 10cm
[[file:fig/test1.png]]

I donnot know how to after? The ":environment" and ":option" seems not to work after the try, no "\begin{minipage}[b]{0.6\textwidth}" showed in the out .tex file

I want to generate ODT file meanwhile, so I left the picture as the link format.

Thanks very much.
