Looking for photos I may have shared with you? There are probably Loads on Google Photos that you could be looking at.
You can access Google Photos through a web browser or use their Mobile App. The app is pre-installed on most Android phones and is a free download for Apple/iOS.
The app has the advantage of notifying you when new things are shared.
🖥 In a web browser:
Just open https://photos.google.com/sharing/ 👈this link. You'll see any photos that have been shared with you, as well as any you have shared with others.
The Sharing button is the one on the far right at the bottom, like the image below. Just give it a click!
