Not yet. It's a nip I tried to introduce before kind20 existed. The nip basically allows to use an image from a kind 1 and reference the kind 1 in a kind 1183 event.

Kind 20 events are new image types that clients need to support. The media feed in the middle in amethyst shows them and olas shows them.

In the next version of amethyst kind 20 will also be added to the gallery, when posting on olas of via the media feed.
