Taustakuva

This policy allows you to configure the wallpaper image that is shown on the desktop and on the login screen background for the user. The policy is set by specifying the URL from which Google Chrome OS can download the wallpaper image and a cryptographic hash used to verify the integrity of the download. The image must be in JPEG format, its file size must not exceed 16MB. The URL must be accessible without any authentication.

The wallpaper image is downloaded and cached. It will be re-downloaded whenever the URL or the hash changes.

The policy should be specified as a string that expresses the URL and hash in JSON format, conforming to the following schema:
{
"type": "object",
"properties": {
"url": {
"description": "The URL from which the wallpaper image can be downloaded.",
"type": "string"
},
"hash": {
"description": "The SHA-256 hash of the wallpaper image.",
"type": "string"
}
}
}

If this policy is set, Google Chrome OS will download and use the wallpaper image.

If you set this policy, users cannot change or override it.

If the policy is left not set, the user can choose an image to be shown on the desktop and on the login screen background.
