python下载图片出现IOError

 import urllib2 
from BeautifulSoup import BeautifulSoup

page = urllib2.urlopen('http://bbs.hupu.com/13608969.html') 
contents = page.read() 
soup = BeautifulSoup(contents)
img=soup.findAll('img')
print img
print len(img)
for myimg in img:
    link=myimg.get('src')
    print link
    content2 = urllib2.urlopen(link).read()   
    with open(u'E:\img'+'/'+link[-11:],'wb') as code:
        code.write(content2)

能下载两张图，然后出现下面的错误
