Fetch image is a poor example

Fetching an image is a poor example of an action which you would react to neither upon success nor failure. A better example may be posting an update or sending a ping.

Also, the example seems contrived when there is a check for success == nil && failure == nil for posting an image. A real world application would never do this.
