OK, so maybe now is the time to understand clearly, how to use python to download image file from the HTML page

#-*- coding:utf-8 -*-
import re
import requests
def dowmloadPic(html,keyword):
	pic_url = re.findall('"objURL":"(.*?)",',html,re.S)
	i = 0
	print 'the keyword:'+keyword+'picture，is downloading...'
	for each in pic_url:
    	print 'downloading the'+str(i+1)+'picture and store at:'+str(each)
    	try:
       		pic= requests.get(each, timeout=10)
   		except requests.exceptions.ConnectionError:
       		print 'error'
       		continue
   		string = './data/boss/' + str(i) + '.jpg'
   		#resolve the problem of encode, make sure that chinese name could be store
   		fp = open(string.decode('utf-8').encode('cp936'),'wb')
   		fp.write(pic.content)
   		fp.close()
   		i += 1
	
if __name__ == '__main__':
	word = "新垣结衣"
	url = 'http://image.baidu.com/search/flip?tn=baiduimage&ie=utf-8&word='+word	+'&ct=201326592&v=flip'
	result = requests.get(url)
	dowmloadPic(result.text,word)

Above is the most common code to download picture from internet and store at local. You can find the source code here

However,if we want to go to next page? or use mutilthread to download?
