title: Retrieve all image files using Dropbox Core API
body: <p>I am working on Dropbox Core API with Google App Engine (python). There seems to be some problems with Dropbox-python-sdk on GAE. Therefore, I have choose to use the Core APIs directly.</p>
  
  <p>My app is trying to retrieve all image files from a user's dropbox (with file type permission). But I couldn't find a way to get all files without specifying the root/path (all the APIs stated <a href="https://www.dropbox.com/developers/core/docs" rel="nofollow">here</a> requires a specific file path)</p>
  
  <p>Any idea?</p>
