John Rozum is known to comics fans primarily for his horror work, from the current Xombi and recent Hangman for DC Comics to creator-owned work like Midnight, Mass. and licensed comics like The X-Files and even Scooby-Doo. He's also the World's Biggest Halloween Fan. The holiday, not the movie. Though I supposed he likes the movie, too. I should ask him.
Anyway, Rozum's started a new blog, The Grim Gallery in which he shares images from his extensive collection of horror photos and art. Like the Dave McKean piece above. It's just getting started, so horror fans can catch up quickly, but Rozum's updating daily, so there'll be plenty to keep you coming back.
