I find the cover for
Load by Metallica to be a horrid choice for cover art, especially if you know what the image is.
Here's a description of the image from Wikipedia:
The cover of the album is original artwork entitled "Semen and Blood III." It is one of three photographic studies by Andres Serrano created in 1990 by mingling the artist's own semen and bovine blood between two sheets of Plexiglas. The liner notes simply state "Cover art by Andres Serrano" rather than listing the actual title of the work.
Yuck. Why put that on a cover. I have the album. I use the image on the back of the CD case as my cover art image.
