Flickr's new virtual reality app, Flickr VR, does just that. The app works with Samsung Galaxy smartphones and the Oculus-powered Samsung Gear VRheadset, allowing you to view Flickr photos in an immersive 360-degree experience.
If you don't have a Gear VR or Samsung Galaxy smartphone, you can still view 360-degree photos on the web, too. Supported photos will start rotating when you visit them. You can use your mouse to click and drag around the photo.
