Photo frame
Make a free digital photo frame
An old tablet, a spare laptop or a smart TV with a web browser makes a perfectly good photo frame. Random Slideshow shows your Google Photos album or Google Drive folder in random order, full screen, and picks up new photos on its own.
Tips for each device
Tablet (iPad or Android)
Plug it in and place it on a stand. The slideshow asks the browser to keep the screen on while it plays. If your tablet still dims, raise the screen timeout in its display settings. Adding the page to the home screen gives it its own icon.
Smart TV or TV box
Open the link in the TV's web browser, or cast a browser tab from your laptop or phone. On a TV, 30 seconds or more per photo feels calm and natural.
Old laptop
Open the slideshow in a full-screen browser window and turn off sleep while it's plugged in.
Keeping it fresh: whoever has access to the album or folder can add photos from their phone, and the frame shows them within a few minutes. It's a nice way for grandparents to see new family photos.
