Load protected image from API

I am using EmberJS along with ember-simple-auth and ember-data to authenticate and retrieve data from my API. One of my models contains properties that point to image URLs. I'd like to display these images in my app. I can do this using

<img class="thumbnail" src="{{user.thumbnail}}" />

The problem is that the images are protected and need an "Authorization" header to be set without which the API returns a 401. I thought about adding the token to the URL as a query parameter and modifying the API to accept it but it seems like a bad idea because the auth tokens will be present in the logs. Is there an EmberJS way of retrieving an image from a secured API?
