I am in the process of creating a public shared Site with a public Group and have added a Gallery to the layout. In the settings I selected to display Apps. Under Style if I select Use Thumbnails is where I have the issue.
When I go to view my Site and am logged into our Portal, the thumbnails display just fine. But when I log out and refresh, looking at the site like a public viewer would, the thumbnails become broken. The thumbnails on the StoryMap applications in My Content have been tried as URLs and as local files and neither makes a difference.
Anyone experience this? I can use the Icon Style, but its just not what I'm looking for.
