Welcome to Android Central! If you're trying to save images from the Google search app (as opposed to the Google website on your browser), then you have to go to Settings>Apps first, select the Google app, then Permissions, and turn on Storage permission. Then your downloaded images will go to the /Downloads folder, which you can then easily access.
