title: How to return random items RESTfully?
body: <p>My design exposes two kinds of resources:</p>
  
  <ol>
  <li>Images</li>
  <li>Tags</li>
  </ol>
  
  <p>I would like clients to be able to request random images by their tag(s). For example: Give me random images that are tagged with "New York" and "Winter". What would a RESTful design look like in this case?</p>
