 ## Examples
 
-In our [Fetch Request example](https://github.com/mdn/dom-examples/tree/main/fetch/fetch-request) (see [Fetch Request live](https://mdn.github.io/dom-examples/fetch/fetch-request/)) we
-create a new `Request` object using the constructor, then fetch it using a
-{{domxref("Window/fetch", "fetch()")}} call. Since we are fetching an image, we run
-{{domxref("Response.blob")}} on the response to give it the proper MIME type so it will be
-handled properly, then create an Object URL of it and display it in an
-{{htmlelement("img")}} element.
