title: Load and show an image from the web in Python with Gtk 3?
body: <p>I'm writing an app on Ubuntu 12.04 with Python and GTK 3. The problem I have is that I can't figure out how I should do to show a Gtk.Image in my app with an image file from the web.</p>
  
  <p>This is as far as I have come:</p>
  
  <pre><code>from gi.repository import Gtk
  from gi.repository.GdkPixbuf import Pixbuf
  import urllib2
  
  url = 'http://lolcat.com/images/lolcats/1338.jpg'
  response = urllib2.urlopen(url)
  image = Gtk.Image()
  image.set_from_pixbuf(Pixbuf.new_from_stream(response))
  </code></pre>
  
  <p>I think everything is correct except the last line.</p>
