Thanks a lot, this works fine now!

But I experienced another issue with respect to images scaling in the odt
export:

This subtree:

======== test.org ==========================
* Test image scaling in odt
#+caption: bar
#+label: fig:bar
#+name: bar
#+attr_odt: :width 8
#+header: :file bar.png
#+header: :width 7200 :height 3600 :res 600
#+begin_src R :exports results :results graphics
  plot(1:10, 1:10)
#+end_src

#+caption: baz
#+label: fig:baz
#+name: baz
#+attr_odt: :scale 0.5
#+header: :file baz.png
#+header: :width 7200 :height 3600 :res 600
#+begin_src R :exports results :results graphics
  plot(1:10, 1:10)
#+end_src
======================================

exports to this: http://i.imgur.com/sUHQi.png on my system.

Thanks for this.  For two reasons that does not work for me:
(1) I want to use captions on my images
(2) it is odt-export specific

+1.  And ideally generic enough, s.t. also the LaTeX supports it.
Beamer has the concept of columns, which is nicely supported in org
mode.  Maybe that could be a general concept supported by all (or, most)
exporters?
