Photo only visible as icon, not the picture itself

I have Win10 local C: SuiteCRM 7.5.3 (from Bitnami stack installer) , works great and I see the photos of the persons.

Upon upgrading from the SuiteCRM website download, to 7.6.6. … all contacts/accounts OK, but I see not the Photo (of the Contact)
anymore ,only yellow/blue ICON in Listview, Tried to fix it in Explorer /Chrome but not yet visible.
In edit I see the correct “Donald.PNG” and in the listing of the Explorer (outside CRM) I see all the photo’s of the contacts in C:\Photos

How come ??


Anybody knows the solution ??
