This must be a [Schema.org type](http://schema.org/docs/schemas.html), and will probably usually be something like [`BlogPosting`](http://schema.org/BlogPosting), [`NewsArticle`](http://schema.org/NewsArticle), [`Person`](http://schema.org/Person), [`Organization`](http://schema.org/Organization), etc.
   * `links` - An array of other URLs that represent the same thing that this page represents. For instance, Jane's bio page might include links to Jane's GitHub and Twitter profiles.

 ### Customizing image output
 
 For most users, setting `image: [path-to-image]` on a per-page basis should be enough. If you need more control over how images are represented, the `image` property can also be an object, with the following options:
 
 * `path` - The relative path to the image. Same as `image: [path-to-image]`
-* `url` - The path to the image to be used in the JSON-LD image object `url`.
 * `twitter` - The relative path to a Twitter-specific image.
 * `facebook` - The relative path to a Facebook-specific image.
 * `height` - The height of the Facebook (`og:image`) image and JSON-LD image object.
 * `width` - The width of the Facebook (`og:image`) image and JSON-LD image object.
