title: Images download with BeautifulSoup
body: <p>I am using BeautifulSoup for extracting pictures which works well for normal pages.
  Now I want to extract the picture of the Chromebook from a web page like this</p>
  
  <p><a href="https://twitter.com/banprada/statuses/829102430017187841" rel="nofollow noreferrer">https://twitter.com/banprada/statuses/829102430017187841</a></p>
  
  <p>The page apparently contains a link to another page with the image. Here is my code for downloading an image from mentioned link but I am only getting the image of the person who posted the link.</p>
  
  <pre><code>import urllib.request
  import os
  from bs4 import BeautifulSoup
  
  URL = "http://twitter.com/banprada/statuses/829102430017187841"
  list_dir="D:\\"
  default_dir = os.path.join(list_dir,"Pictures_neu")
  opener = urllib.request.build_opener()
  urllib.request.install_opener(opener)
  soup = BeautifulSoup(urllib.request.urlopen(URL).read())
  imgs = soup.findAll("img",{"alt":True, "src":True})
  for img in imgs:
     img_url = img["src"]
     filename = os.path.join(default_dir, img_url.split("/")[-1])
     img_data = opener.open(img_url)
     f = open(filename,"wb")
     f.write(img_data.read())
     f.close()
  </code></pre>
  
  <p>Is there an opportunity to download the image somehow?</p>
  
  <p>Many thanks and regards,
  Andi</p>
