Wallpaper image

If you set the policy, Google Chrome OS

downloads and uses the wallpaper image you set for the user's desktop and sign-in screen background, and users can't change it. Specify the URL (that's accessible without authentication) which Google Chrome OS

can download the wallpaper image from, as well as a cryptographic hash (in JPEG format with a file size up to 16 MB) to verify its integrity.

If not set, users choose the image for the desktop and sign-in screen background.
See https://cloud.google.com/docs/chrome-enterprise/policies/?policy=WallpaperImage for more information about schema and formatting.

Example value:

{
"url": "https://example.com/wallpaper.jpg",
"hash": "baddecafbaddecafbaddecafbaddecafbaddecafbaddecafbaddecafbaddecaf"
}
