title: Remote image as notification icon in Chrome Packaged App?
body: <p>I'm writing this app and would like to display Chrome notifications with certain remote images as notification icons.</p>
  
  <p>I am aware that you are not allowed to directly assign the URL of a remote image as the notification icon, so I assume I would first have to download the remote image via some sort function and then use the now local image as a notification icon.</p>
  
  <p>How could this be achieved?</p>
  
  <p>Thanks in advance</p>
