Couldn't you set it up to save this information under the Artists folder (or Sub-folder)? So Skin authors have a standard location where to find this information? Similar to how CULyrics creates a folder under the Artists called Lyrics, or Artist Slideshow uses the extrafanart folder under the Artist to store extra fanart.  

Sorry, I should have been clearer.  AS sets a series of window properties that any skin can use.  So AS is already providing skin authors a set of standard things they can plug into their skins.  Where the actual data is stored on the disk is controlled by AS, but it doesn't really matter, as AS reads it as needed and, again, puts it someplace the skin author can easily get to.  

 So AS does store the data somewhere, but you say it doesn't really matter. When in fact, it does matter.

Since I have multiple Kodi installs around the house, this means that each install, will have to re-download this data again. So it now takes up space on my devices (since AS is keeping the data locally, instead of on my NAS), it's more of a burden to the makers of said data (since they will have multiple machines trying to grab that data, and someone needs to pay their bandwidth bills), and there is no place for me to locate said data, (to add, edit, or whatever) to that information.

Having this data stored in the location the rest of the Artist data is, just makes a whole lot more sense for everyone. 

 OK, I know I didn't update the wiki, but this option did get announced with the new version and is listed in the change text when you view the information on the addon.  Please make sure you are running the most current version (2.1.1) and check the settings.  In SLIDESHOW you'll see a toggles for using the local artist path for all artist images and the text information.  It can take awhile to migrate all that data, so I'd recommend doing it on one machine (just run AS manually from the program menu) until it's done, then do the next.  You'll end up with everything in one place.
