title: Openstack python API: how to download image from glance using the python api
body: <p>I am trying to write a python program to download images from glance service. However, I could not find a way to download images from the cloud using the API. In the documentation which can be found here: </p>
  
  <p><a href="http://docs.openstack.org/user-guide/content/sdk_manage_images.html" rel="nofollow">http://docs.openstack.org/user-guide/content/sdk_manage_images.html</a> </p>
  
  <p>they explain how to upload images, but not to download them.</p>
  
  <p>The following code shows how to get image object, but I don't now what to do with this object:</p>
  
  <pre><code>import novaclient.v1_1.client as nvclient
  name = "cirros"
  nova = nvclient.Client(...)
  image = nova.images.find(name=name)
  </code></pre>
  
  <p>is there any way to download the image file and save it on disk using this object "image"?</p>
