Beamer \usebackgroundtemplate - better solution?

Hi

I am using the following structure for \usebackgroundtemplate in Beamer:

--8<---------------cut here---------------start------------->8---
*** Overview of The Case Study
:PROPERTIES:
:header-args: :eval never-export 
:header-args+: :file-ext pdf
:END:
#+LATEX: {
#+LATEX: \usebackgroundtemplate{

#+ATTR_LATEX: :width 1\paperwidth :height 1\paperheight :options keepaspectratio
     [[./bramble2.jpg]]
#+LATEX: }

**** Some slide
  - one
  - two
  - three

*** 
#+LATEX: }
--8<---------------cut here---------------end--------------->8---

which works, but I don't like it that much because of the disconnected
nature of the beginning (in the header Overview...) and the closing
bracket (in the header without text). Also, this header without text is
rather fragile, as using tab on it, indents the header and does not fold
(cursor has to be on the stars to fold).

I assume that I can use org-beamer-environments-extra, but I don't
really see how (I would like to have the image as an argument).

I saw http://orgmode.org/worg/exporters/beamer/ox-beamer.html but this
does not help me with using the image as an argument.

Any suggestions?

Thanks,

Rainer

Could you use headings that are ignored to make the layout more obvious?
I do the following in documents, for instance:


--8<---------------cut here---------------start------------->8---
** (new page)    :ignoreheading:
#+latex: \newpage
--8<---------------cut here---------------end--------------->8---

with an appropriate filter that removes the headline with the
ignoreheading tag from the export.
