Filter images from tweets

Question

I have reduced to tweepy, and I'm wandering about how you can track and save the image that the user posts on his tweets. I found several ways in the tutorials to get custom tweets, but I could not find a way to filter only images.

I use the following code to get custom tweets. How can I get only custom images?

EDIT: I am editing my code as shown above:

auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_access_token(OAUTH_TOKEN, OAUTH_SECRET)
api = tweepy.API(auth)
timeline = api.user_timeline(count=10, screen_name = "zenitiss") 
for tweet in timeline: 
   for media in tweet.entities.get("media",[{}]):
      print media
      #checks if there is any media-entity
      if media.get("type",None) == "photo":
          # checks if the entity is of the type "photo"
          image_content=requests.get(media["media_url"])
          print image_content

However, the for loop seems to not work. A print line prints a null object. Basically, when I try to print user urls like karyperry, I get:
