Ah, yeah... I kind of remember this problem from when I was messing around with Kodi myself. So, actress images are stored centrally in the JavLuv settings folder, to avoid redundant storage, and for editing (like adding alternate images of the actress. However, Kodi seems to expect the actor filename to be local, and stored in the same folder as the movies, or maybe in a fixed sub-folter... I forget which exactly, but it's kind of picky about that.
At the moment, there's no way for JavLuv to do this. Could it be done? Yeah, I think so. I mean, I was pretty careful to make sure the movie metadata file followed the Koki format. I'd need to add some sort of "Koki mode" that would apply some special rules for actresses, or something like that. Will that be done? Unfortunately, I haven't had much spare time to add new features over the past year, except very basic maintenance and bug fixes. It would certainly be cool to offer actual compatibility with the Kodi app, but I really can't promise any timeline for this.
Another issue II remember is that Kodi expects a description for the movie to display fairly prominently, and unfortunately, none of the scraping sites I use consistent have anything of the sort to scrape. So, I ended up using the movie description field as 'Notes". It's going to leave a fairly large blank spot when displaying movies in Kodi, but I don't think there's much I can do about this.
I've added an issue in GitHub to track this feature request:
Add an option for storing actress images in a Koki app compatible method, which means storing a copy of actor images inside the movie folder (in an actor folder?), if I recall correctly.
