Google Photos tests feature to show curated albums on smart displays
You want to show off photos on your smart displays or Chromecast-connected devices? Google Photos is testing out a new feature called Photo Frames for this specific function. It's available in version 4.32 of the app. And it's accessible on the left sidebar. When you select this option, it'll show you a list of Chromecasts or smart displays in your vicinity. Once you've chosen the device you want to display photos on, you can pick the album you want it to show.
