I recently created a shortlist story map using images that were hosted within my ArcGIS Online Organisation. Since creating the story map a number of the images have become inaccessible and the story map reports that it has issues. When I investigate those issues, I can open the link just fine and the image loads.
My only thought is that the image is larger than recommended for the thumbnail. I will eventually rectify this but it was working fine up until today.
Has anyone run into this before, and how do I fix it? My story map is public and available here: http://arcg.is/55fvv
