Can't find an image of osmc/kodi17.6 (krypton)

Can’t use my add-on anymore because kodi went up automatically to 19.4 which is not supported anymore. since then looking for an osmc/kodi 17.6 but unable to find one.
ha somebody an image of osmc/kodi17.6 ?
thank you so much !!!

OSMC won’t update without your consent. 17.6 → 19.4 isn’t a supported upgrade path either. Are you sure you are using OSMC?
