Google Photos is a cloud storage space to back up and store photos & videos. It organizes the photos automatically and lets you access them on any device. As LG Smart TV doesn’t have the Google Photos app, you can visit the web version of Google Photos to view the pictures and videos on a big screen. Alternatively, you can cast the Google Photos app on your TV from an Android Phone or iPhone.
