Python Imaging Library (abbreviated as PIL) is a free library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats.

Pillow is the "friendly" PIL fork by Alex Clark and Contributors. And the lasted Pillow version can be downloaded from here.

目前，Pillow的最新版本是2.7.0，在图 1中选择与已安装Python对应的exe文件，我的Python是32bit2.7.3，所以对应图 1中的安装文件，下载它。

下载后，双击文件开始安装。

安装成功后，在Python IDLE键入from PIL import Image再回车，若无错误，即是安装成功。
