    pic_start = content.find('\xff\xd8\xff\xe0', start)
    if pic_start == -1:
        break
    start = pic_start + 1
    while True:
        first_start = content.find('\xff\xd8\xff\xe0', start)
        first_end = content.find('\xff\xd9', start)
        if first_start != -1 and first_start < first_end:
            start = first_end + 1
        else:
            break
    pic_end = first_end
     
    cnt += 1
    fp = open('%d.jpg' % cnt, 'wb')
    fp.write(content[pic_start:pic_end + 2])
    fp.close()
    start = pic_end + 1
