The instillation is OK. The problem is that on my wok PC I do not have PIL installed. So:
In [6]: import scikits.image.io as io
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

      9                       "Please refer to http://pypi.python.org/pypi/PIL/ "
     10                       "for further instructions.")

ImportError: The Python Image Library could not be found. Please refer to http://pypi.python.org/pypi/PIL/ for further instructions.

Shouldn't it skip quietly on missing plugins?
(It is easy to bypass by a patch, but  I am sure you has some design considerations here.

Thanks so much for testing and for the patch; I've pushed your changes:

https://github.com/stefanv/scikits.image/commit/b47ae98ffb92e2de33d9e530201e402e04d865d3

Are you able to load images now?

Cheers
Stéfan
