    url=raw_input('please input the website you want to download:')
    imgcontent=urllib.urlopen(url).read()
    urllist=re.findall(r'src="(http.+?\.jpg)"',imgcontent,re.I)
    if not urllist:
        print 'not found...'
    else:
        filepath=os.getcwd()+'\img1'
        if os.path.exists(filepath) is False:
            os.mkdir(filepath)
        x=1
        print 'begin to get pictures...'
        for imgurl in urllist:

            print 'it is downloading the %s pictures'% x
            print imgurl
            urllib.urlretrieve(imgurl,temp)
            x+=1
    print 'download completely...is saved at '+filepath
