When I turned on my iMac this morning, the wallpaper on both the primary and secondary (external) screen had unexplainably reverted to the default one (pictured).

I did absolutelly nothing out of the ordinary last night. Anyone ever experience this?

EDIT:

Could a mod please change the title of this thread to:

"OS X desktop unexplainably reverted to default Mavericks wallpaper"

Thank you kindly.
