Currently if one use something in a rst file like:
.. image:: http://www.example.com/foo.png
And passes it to rst2odt, the image is not included in the document, showing instead the following warning:
(WARNING/2) Cannot find image file http://www.example.com/foo.png
It would be nice if the image could be fetched and included in the document. Currently rst2pdf does it by using urllib.urlretrieve if it detects a HTTP URI.
