how to install PILLOW module

I want to start working on incorporating images into my tkinter application to make it look all snazzy and what not. And Ive learned that i need to add an external module to my python installatin (2.6 btw) in order for it to work. I downloaded the file and its a .whl extension. I dont even know what that is, much less how to properly install it. the name of the file I downloaded is “Pillow-2.2.1-cp26-none-win32.whl”. so my question is, how do I install it?

What wheel is:

You also can just download the Windows Installer package instead.

i didnt even see the ms installer lol thanks man
