import os

urls = (
'/images/(.*)', 'images' #this is where the image folder is located....
)
class images:
def GET(self,name):
ext = name.split(".")[-1] # Gather extension #<span style="color:#33FF33;">返回获取的所有子字符串</span>

cType = {
"png":"images/png",
"jpg":"images/jpeg",
"gif":"images/gif",
"ico":"images/x-icon"            }

if name in os.listdir('images'):  # Security
web.header("Content-Type", cType[ext]) # Set the Header
return open('images/%s'%name,"rb").read() # Notice 'rb' for reading images
else:
raise web.notfound()
app = web.application(urls, globals())
if __name__ == '__main__':
app.run()

在../serving_images/目录下创建images/目录，将你想要显示的图片放到该目录下，注意文件格式。然后，

python serving_images.py

登陆http://localhost:8080/image_name.png，即可提供图片下载查看功能。
