Also it was a pain finding the right PIL library, your link did not provide the right info. I think you meant:

http://www.pythonware.com/products/pil/

not,

http://www.pythonware.com/library/pil/

Even then it link for 2.7 was not working so i searched the internet. Apparently something named PILLOW took it place but i still manage to find the right library here: http://christianakesson.com/compiling-pil/ at the bottom of the article.

Still not working though...
