Desktop Covered with Thumbnail Photos - How to Revert to Standard Desktop
One of my family members did something to cause his iMac to fill his desktop with photo thumbnails. He is not sure what he did to make this happen and I haven't a clue what to tell him to get his desktop to revert to the standard desktop. We've tried rebooting, logging off and back on, etc., but each time he logs on to his desktop, the photo thumbnails reappear. The photos seem to be from his photo collection or library or maybe his Dropbox backup.
Can anyone tell me what we are seeing here and how to get remove the thumbnails from his desktop?
Here is a pic of how the desktop appears with the photo thumbnails.
Thanks in advance for any assistance!
