 * `image_size`: The size of the user's profile picture. The image returned will have width equal to the given value and variable height, according to the `image_aspect_ratio` chosen. Additionally, a picture with specific width and height can be requested by setting this option to a hash with `width` and `height` as keys. If only `width` or `height` is specified, a picture whose width or height is closest to the requested size and requested aspect ratio will be returned. Defaults to the original width and height of the picture.

-* `access_type`: Defaults to `offline`, so a refresh token is sent to be used when the user is not present at the browser. Can be set to `online`. Note that if you need a refresh token, google requires you to also to specify the option `prompt: 'consent'`, which is not a default.
