Playing RAW pictures in Kodi v. 17

Hi i’m a W10 user and first off my life installed Kodi v17. I did get my jpeg photo’s but not my RAW format’s. Then removed v17 and installed v16. 1. I heard and it works.
When is the solution for RAW (Nef from Nikon) comming to Krypton and/or do I have to install the Plex add-on in v17? Maybe the last thing has nothinv to do with showing RAW in Krypton?
