Object Media overlay not showing image for some objects

RHEL7/Apache/2.4.25 (Red Hat) OpenSSL/1.0.1e-fips PHP/7.0.10 /mysqlnd 5.0.12-dev/elasticsearch 5.5.1-1

Some of our object representations don't generate on the overlay that comes up when you click the image thumbnail (which shows just fine) on the object's screen (see image). Interestingly, you CAN download the image from the overlay; and, if you "Edit full record" for the representation, everything works as it should on the Representations screen.

Users report that this is not limited to image type (jpgs, tifs). Looking in the ca_objects and ca_objects_x_object_representations tables, these records appear to be the same as records without this issue.

Wondering if anyone has seen this before? Recommendations gratefully accepted.

Thank you,
John

  • Hi John,

    The default settings in media_display.conf are sometimes set to trigger a different media viewer if there are more than 4 or so images.  If this is happening on records with more than a handful of representations, you may be accidentally triggering a media viewer you haven't properly configured to work with your system.
  • More specifically try removing the lines in media_display.conf with use_universal_viewer_for_image_list_length_at_least or use_mirador_for_image_list_length_at_least
    If it works then, then we at least know roughly where the issue lies.

  • Hi Sophie and Seth,

    Success! That looks like it's solved it.

    "use_universal_viewer_for_image_list_length_at_least = 3" was already commented out, so I commented out "use_mirador_for_image_list_length_at_least = 3" also; and now  media_display.conf looks like:

    #use_universal_viewer_for_image_list_length_at_least = 3
    #use_mirador_for_image_list_length_at_least = 3

    Everything is now working as expected.

    Thank you so much for the help,
    John
