Hi all,

I've found that this has come up in the past, with no real solution.
I have found a workaround though.

First the issue at hand:

Beamer allows for setting the background image by setting 
setbeamertemplate *outside* of the frame environment:

#### begin tex src snippet
% preamble

{	% by enclosing it in a tex environment
	%the background is set only for this frame

\setbeamertemplate{background canvas}{
	\includegraphics[width=\paperwidth]{./myImage.jpg}
	}

\begin{frame}
\frametitle{Outline}
\setcounter{tocdepth}{3}
\tableofcontents
\end{frame}

}`	% end tex env

#### end tex src snippet

A quick look at org-beamer.el makes me think that there is no 
infrastructure in place that accounts for enclosing each frame in its 
own tex environment, although I think that would be trivial.
Less trivial for me is what kind of structure should be in place that 
inserts the code before the frame.
A property for sure...

Any thoughts on this ?


Anyway, the workaround is using the "wallpaper" package and set the 
beamer background canvas to nil:
\usepackage{wallpaper}
\setbeamercolor{background canvas}{bg=}

then in org:
* my slide title:
\ThisCenterWallPaper{1}{myImage.jpg} % first argument is scaling

But, a solid Org-beamer implementation like described above is preferred...
