Hi @jason-c-child, Thanks for the pull request. When https://github.com/keystonejs/keystone/pull/8816 is merged, could you extend the example to demonstrate how you used this feature?

I agree it is generally undocumented except by the generated GraphQL schema:

input CloudinaryImageFormat {
  """ Rewrites the filename to be this pretty string. Do not include `/` or `.`
  """
  prettyName: String
  width: String
  height: String
  crop: String
  aspect_ratio: String
  gravity: String
  zoom: String
  x: String
  y: String
  format: String
  fetch_format: String
  quality: String
  radius: String
  angle: String
  effect: String
  opacity: String
  border: String
  background: String
  overlay: String
  underlay: String
  default_image: String
  delay: String
  color: String
  color_space: String
  dpr: String
  page: String
  density: String
  flags: String
  transformation: String
}

type CloudinaryImage_File {
  id: ID
  filename: String
  originalFilename: String
  mimetype: String
  encoding: String
  publicUrl: String
  publicUrlTransformed(transformation: CloudinaryImageFormat): String
}
