/**
 * Creates a new Request configured to upload an image to create a staging resource. Staging
 * resources allow you to post binary data such as images, in preparation for a post of an Open
 * Graph object or action which references the image. The URI returned when uploading a staging
 * resource may be passed as the image property for an Open Graph object or action.
 *
 * @param accessToken the access token to use, or null
 * @param file        the file containing the image to upload
 * @param callback    a callback that will be called when the request is completed to handle
 *                    success or error conditions
 * @return a Request that is ready to execute
 * @throws FileNotFoundException
