Honestly, I have not messed with it in a while. Issue I was having is the LB Arcade - Marquee images defaults to a users Box - Front image priority is a marquee is not present and no matter what I tried it always displayed either the existing marquee image or the priority fallback. Even if I coded in a FallBackValue it still gave LB built in priorities preference. Hopefully next poll go round Marquee update can get voted more and it gets some updates.
I can get it to work if Arcade - Marquee images are in a custom folder location, but that is just an unneeded workaround. I will mess with it again. Maybe I have learned more in the time and can get it to work.
