have a look at https://blog.busitec.de/office-365-bilder-verwalten-mit-sharepoint-online/
the view layout in step 4 ist what i got in april when i created an image or asset library.
but i just tested it today an it's gone.
Does anyone have a similar issue or does know a comuninication of Microsoft that the view layouts are gone?
I also checked different tenants, same issue (if it is an issue... perhaps a featue?)
perhaps there is anew cross to activate it?!
