In Exhibition, some of the TN images are not loading in IE 11 browser even those the TN exists in the repository. This was in IE 11.0.9600.18314 and tried clearing out browser cache and refresh the page multiple times. Other browsers like FF, Chrome, Safari loads the TN image correctly. This was happening for the Exhibition page - http://exhibition.sidora.si.edu/fedora/repository/si:2757402
