Picture Slideshow Screensaver and band/artist name i wrong

I have Picture Slideshow screensaver installed and I scrapped image to a local directory (as I do not want the screensaver to go out on internet for every picture again, and that did not either got right band/artist info out),  from Fanart and then load pictures from that directory, to the screensaver. The problem is that I want to have directory name out (that looks right), as it is the same as music band/artist picture, but fanart created a directory called extrafanart in every band/artist  directory, so i just got extrafanart repeatedly as band/artist name (as picture info).  How can I fix this in an easy way, without having to move up every picture one step in directory structure (and delete the extrafanart directory)?
