You don't need to explicitly specify a return when working with a
session.  Either of the following should work.

    #+BEGIN_SRC python :session test :file "images/test.png"
      from pylab import *
      plot(rand(10))
      savefig('images/test.png')
    #+END_SRC

or

    #+BEGIN_SRC python :session test :results file
      from pylab import *
      plot(rand(10))
      savefig('images/test.png')
      'images/test.png'
    #+END_SRC

Hope this helps,
