JIRA will not display images with the wrong MIME type in IE due to nosniff header



      Since 5.1.2, JIRA specifies "X-Content-Type-Options: nosniff" in the headers of all pages. This means that IE will not display any image which was uploaded with the incorrect MIME type. It's hard to reproduce this issue when uploading new images as they are automatically converted to PNG, however any images uploaded in previous versions before this was done are affected. It may also be possible to get such images into JIRA by specifying the wrong MIME type in a REST API request.

      Steps to Reproduce

      1. Find any image file in JIRA which has the wrong MIME type
      2. Try to view it in IE


      Re-upload the image so that it gets converted to PNG.
