Hi Darlan.
Thanks for you response.
I am aware of the working folder differences and use absolute path in
my scripts.
I have found a workaround  in this mailing list:
This solves my problem with inline images in results. Have not tried
exports yet.

#+begin_src python :results output raw :exports results
  import numpy, matplotlib, matplotlib.pyplot
  figure = matplotlib.pyplot.figure()

  axes = figure.add_subplot(111, title=u"Hello", xlabel="x", ylabel="y")

  x = numpy.arange(-10, 10, 0.1)
  axes.plot(x, x**2)
  print "["+"[/tmp/plot_test.png]]"
