Hi! I have a surface RT. I downloaded an app which puts a slideshow of famous paintings as your locked screen display. A few days later it stopped working and paused on this terrible painting of an angel taking a dead man to heaven... so I went to change pc settings and changed the photo but when I went to the locked screen it was the same painting. So I clicked show ‘file1’ (a file I had created with different photos) as a slideshow on locked screen- but that didn’t work either. So then I deleted the app and tried the above again- no hope. So then I refreshed the settings- you know the setting where it keeps your files intact but refreshes the surface settings- again no hope. I’m fed up of people thinking I’m some sort of creep with this painting as my locked screen display! HELP!!
