解决方法：

到http://www.lfd.uci.edu/~gohlke/pythonlibs/下载pillow，安装

 

然后创建如下代码测试

   1: import os,sys

   2: from PIL import Image  

   3:  

   4: pic = Image.open("test.png")

   5: pic.show()

pip是一个很好的工具，类似apt，可以为python管理模块

缩小图片操作

   1: import os,sys

   2: from PIL import Image

   3:  

   4:  

   5: MAX_WIDTH = 2048

   6: MAX_HEIGHT = 1536

   7:  

   8:  

   9: pic = Image.open("test1.jpg")

  10: width,height = pic.size

  11:  

  12:  

  13: small = pic.resize((width / 2,height / 2))

  14: ##small.show()

  15: small.save("test1_small.jpg")
