Enable Get Image Descriptions from Google.

The Get Image Descriptions from Google
accessibility feature enables visually-impaired screen reader users to
get descriptions of unlabeled images on the web. Users who choose to enable it
will have the option of using an anonymous Google service to provide
automatic descriptions for unlabeled images they encounter on the web.

If this feature is enabled, the content of images will be sent to Google
servers in order to generate a description. No cookies or other user
data is sent, and Google does not save or log any image content.

If this policy is set to Enabled, the
Get Image Descriptions from Google
feature will be enabled, though it will only affect users who are using a
screen reader or other similar assistive technology.

If this policy is set to Disabled, users will not have the option of enabling
the feature.

If this policy is not set, user can choose to use this feature or not.
