A new feature has been launched by google for image search called badges that will help user to find images based on the categories as defined by the google systems. images can be also searched by its source, such as if any image has been pulled from a game or from any video, badge will identifies as it is.
This new feature was first available on mobile web and the google app by google, but it is also available on Pcs web too. This feature will help users save some more time in searching images or videos over the web. Unfortunately this feature is yet not available for any app on apple mobile devices nor google has confirmed the date or month in which this feature will be available to the apple mobile device owners.
Lets hope it will be soon and not too long for apple mobile devices.
