Current core does not support image file stacking out of the box. This change among stacking will add also support for resume and watched status. This has been already available from Media Slayer thread quite a long time without complains so it should be safe to add (note that those files also have share view enhancements which are not included as there might be some issues).
Btw for future reference do you prefer files or just patch format?
