I am on a Netbook and I am unable to create "big" images. This is the
following error I get when export the above snippet.

,---- "*Org-Babel Error Output*"
| Error in png(filename = "baz.png", height = 3600, res = 600, width = 7200) : 
|   unable to start device
| Calls: <Anonymous> -> <Anonymous> -> png -> .External
| In addition: Warning messages:
| 1: In png(filename = "baz.png", height = 3600, res = 600, width = 7200) :
|   Unable to allocate bitmap
| 2: In png(filename = "baz.png", height = 3600, res = 600, width = 7200) :
|   opening device failed
| Execution halted
`----

If I reduce the dimensions of the above images, I see that the ODT
output is along expected lines.

I imagine that for some reasons, the ODT exporter has trouble figuring
out the image dimensions of the second image.

Btw, can you post the outputs of the following forms:

#+begin_src emacs-lisp
  (list (* max-image-size (frame-pixel-width)) 
        (* max-image-size (frame-pixel-height)))
#+end_src

#+begin_src emacs-lisp
    (message "%S" (ignore-errors 
                    (image-size (create-image "bar.png") 'pixels)))
    (message "%S" (ignore-errors 
                    (image-size (create-image "baz.png") 'pixels)))
#+end_src

If you can also post the output of the XML created in your machines, I
would be able to infer what could be happening. 

You can access the XML with:

open odt file in archive-mode: C-x b test.odt or C-x C-f test.odt
open content.xml	     : ENTER on content.xml
search for .png              : C-s .png

Post the snippets for both 001.png and 002.png
