EMAP were the only company who ever replied to me about cover scans and they sent me a written letter giving me permission to use about 30 pages and 3 cover disk images on my site.
With a "if we dont actually own it then you're on your own legally" disclaimer.
P.S. Forget CU DVD, I want an AMR hard drive... the entire site backed up to a cheap £40, 500GB external drive. Just in case something happens to it
