@Marcel, @Angelinas, @meowmoo I really am confused.

I noticed that Album art (cover and cdArt) get saved in my Custom Folder since the last update, I usally keep cdart.png and Album covers with my mp3's in one folder, not a big issue, but if it would be possible to save Album related Art in the Album folder (with the mp3s) and Artist related Art in the custom folder, I would be a happy Cow
also im wondering, what happend if i turn on both option, "save art to local files" and "save art to custom folder". I guess i will get all the art on both places?!

Save Art to custom art working perfect....
Save all Art in folder with your path, same as your music folder or new.
You dont need duplicate art file if you dont want, just set same path as your Music folder
Problem that you will have is name of Album......You will have one name for album , MB scraper will find different , and art for that album will in new folder.
I have album name
-My House Album Leaked [2015]
SHS find name for this album
-My House
Thumb, disc, thumbback and spine for that album will be download to new folder with name "My House".
My House Album Leaked [2015] folder stay in music folder without Art inside.

I set both places (folder and custom folder).
In custom folder download all Art (working as clock)
In folder SHS download missing Art for Artist...for Album dont working download.(if missing Art in folder)

Are you really talking about a Skin Helper Server facility, or about cdART? Sounds like the cdART addon to me, and I can't see any SHS options for folders etc.

I don't use either addon, but I installed to try and see what they do. Please someone be kind and explain.

@ DaveBlake
Iif I Download new Artist & Album SHS download all Art and info For Them.
Download "on fly" Album Art is missing in Kodi..It will be nice to Kodi have power to do this(if missing Art).

I think what I am doing will fix that
Work still in development, but I'll let you know when something to test.
