When you are not using Chromecast to cast videos, it displays a slideshow of high quality images on the screen of your TV. In case you want to, you can change the background on Chromecast, so that it displays your family pictures instead of random pictures.
Change Background on Chromecast
While the idea of displaying your favourite Photos as Chromecast background images is appealing, another good reason for changing the background on Chromecast is to reduce the amount of data consumed by Chromecast background images.
Left to its default settings, Chromecast is set to use your internet connection to download high-quality background images from various sources and display these images on your TV.
However, these images are of such high quality that users have reported up to 40 GB/Month of data being used by Chromecast, even when it is idle. This can be a problem in case you have a data cap.
Luckily, it is easy to change background on Chromecast, and this can be done by first creating an Album in Google Photos and assigning Photos in this Album as Chromecast background images.
Create Album in Google Photos
Follow the steps below to Create an Album in Google Photos for sharing images using Google Chromecast.
1. On your Android Phone or iPhone open the Google Photos app.
Note: iPhone users can download the Google Photos App from the App Store.
2. Once you are in Google Photos App, tap on the Albums tab located at the bottom right of your screen (See image below)
