I back up most of my digital imagery on the computer and all on my google drive since it is so big and my hard disk is full. (Yes I have some external drives too, but they are filling up.
Anyway, on my Dell (Windows 10) I have it set up to do a slide show of pictures. It is set up to randomly show a picture every minute from a preselected folder. For the past month or so, have been enjoying pictures from Iceland and get to see some shots that I totally forgot about.
