title: take and upload picture using Mirror API for Glass
body: <p>while it's possible to send image to glass in a timeline card, it doesn't look like it's possible to to the opposite (take a picture and upload it).</p>
  
  <p>If I'm correct, this operation would be performed as a user action in the mirror APIs (like SHARE, REPLY, NAVIGATE), but I don't see any camera related function.</p>
