...I can add this, I just don't know how to make it easy to understand.
I've thought about it, and I don't know how you could set up the UI to make everyone happy. There will be someone who wants to exlude the slider images on the top level only, but someone else who wants to exclude them on the top 2 or 3 levels, because his album is "all folders" until you get down to level 3 or 4.
It's one of those things that somehow needs to be set at the folder level, but we both know why that's a mess - custom UI, and once you start going down that road, there's just no end to it. Users find all kinds of things that they want to do differently at various folder levels.
