 Rob Sheridan acted as the album 's art director , in collaboration with Artist in Residence . Sheridan was also art director for the previous two Nine Inch Nails studio albums , With Teeth ( 2005 ) and Year Zero . Since Ghosts was released in a variety of versions , some of the versions feature somewhat differing ( or additional ) album art and related artwork . A 40 @-@ page PDF comes with each version of the album and contains a photograph for each of the 36 tracks . These photographs are also embedded into the ID3 tags of every downloadable track .
