read images in python

Hi all, 

do you know whether there is a way in the python console in rhino to import a module to read images?

What I am in need of would be to be able to read an image:

size of the image

color of a given pixel

(png, jpg, bmp, doesn't matter) 

import png doesn't seem to work and I couldn't manage to install PIL. 

Has anyone ever tried to do it? What would be the easiest way to do it?

Thanks in advance

best

Vincenzo
