一、獲取ｕｒｌｓ

登入官網, 　www.image-net.org,　SEARCH自己需要的圖片種類，　以搜尋插座（ｓｏｃｋｅｔ）為例，必須輸入英文（這是廢話）。可能需要翻牆，不一定，如何翻牆請去隔壁下載ＶＰＮ

點選需要的選項進入

點選ｄｏｗｎｌｏａｄｓ標籤，出現ＵＲＬＳ類

點擊出現很可怕的大量ｕｒｌ，下載儲存在ｔｘｔ中備用。

二、ｐｙｔｈｏｎ指令碼批量下載

用ｐｙｔｈｏｎ的ｕｒｌｉｂ庫批量下載獲取的ｕｒｌｓ，此處用的ｐｙｔｈｏｎ２．７環境，程式碼如下

# from urllib import request
import urllib2, urllib
import signal

path ='/home/hzc/Pictures/URL-TXT/watermeter.txt'
 
def handler(signum, frame):
    raise AssertionError
file = open(path)

for line in file:
    try:
        signal.signal(signal.SIGALRM, handler)
        signal.alarm(5)

        print(line)
        # # fake header
        # headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0'}
 
        # req = urllib.request.Request(url=line, headers=headers)
        # urllib.request.urlopen(req).read()
try:
            f = urllib2.urlopen(line)
            data = f.read()
            with open('%s ' % line.split('/')[-1], "wb") as code:
                code.write(data)
        except:
            pass
 
# pic_link = line
        # save_path = r'/home/hzc/Pictures/%s.JPG '% line.split('/')[-1]
        # request.urlretrieve(pic_link, save_path)
except AssertionError:
        print("%s timeout " % line)
        continue
file.close()

得到一大串圖片，重新命名，加標籤的請移步我的另一篇部落格：
