I've noticed that several of my artists that end in period (Carl Dobkins Jr., Grover Washington Jr., Hank Williams Jr.) have no fanart. Does Artistslideshow handle these correctly given that MS Windows does not allow periods at the end of folders? That is to say, all my fanart folders for these artists are period-less.

It should.  I have Harry Connick, Jr. music in my library.  The folder AS creates is Harry Connick Jr and I have art for it.  In the settings under ADVANCED (it's after similar artists, so you have to scroll down) check to see what is set in PLATFORM FOR IMAGE STORAGE.  I can't remember what the default is, but if you set it to Windows that will make sure AS avoids Windows special characters and not put a period at the end of a folder name.
