Guys, that link is nearly 16 years old - so it is not surprising it doesn’t no longer works.
I’m not sure if anyone can help you with these specific covers… but there is a link to some of the cover art which Jetrell Fo did (along with with cover art from other talented people on here which he also saved and kindly made available), in the An Index & Help Thread for Case Covers, Disc Labels, and Fan Art…
Good luck with it 😃
