Publishers should all have a /covers directory →
BoingBoing’s Cory Doctorow:
… publishers should create default directories called “covers” at their server-root (e.g., tor.com/covers, harpercollins.co.uk/covers, etc) filled with high-rez PNGs or JPGs (or both) named after the book’s ISBN — for Neil Gaiman’s Graveyard Book, it would be http://harpercollins.co.uk/0060530928.png. Tweak your robots.txt file to make sure the search-engines all crawl these directories, so when you search on images.google.com or images.yahoo.com for an ISBN, the publisher’s high-rez would be right there at the top.
