I'm new to Python and am trying to install the pyimage module.

I'm on Windows and have downloaded and installed 2.6 and 3.1.

I downloaded pyimage, and used cmd and cd to get to its directory.

I then got this:

cd C:\Users\Jourkey\Desktop\pyimage-0.8.13\pyimage-0.8.13
python setup.py install

Output:

'python' is not recognized as an internal or external command,
operable program or batch file.

How do I install this?
