I noticed that in the Javascript console, the image being requested did not have the required mturk query-parameters appended to it (URL of image). This naturally meant the secure image server was not sending back the image as needed, returning a 404 instead.

Expected behavior
The front-end passes the required query parameters through to the secure image server, allowing workers to authenticate and view private images.
Current behavior
The front-end does not pass the required details, and the response 404s.
