Artist Information

I've set up XBMC to look at my Music files. Its all set up as

Server\Music\FLAC\Artist\Album

All my albums show up great in XBMC with the correct cover art as i have the folder.jpg files in each album folder.

I've downloaded a couple of Artist info scrapers (Musicbrains and allmusic) and done what i think i need to to, to set up images for Artists but they still just seem to be blank. Is there any tutorials out there to sort this out?

Cheers
