Long ramble short: I'm putting up past headers because I never use them twice, and thought maybe somebody would get some use out of them. Some are scary, some I'm happy with, one I have no idea what I was thinking besides "Ooooh, shirtless Hugh Jackman as Wolverine."
Under the cut shown using thumbnails (this post might be slightly image-heavy):
Movies: Wolverine, X2, X3, Jack/Elizabeth, Oliver Wood, Dumbledore/Snape/Draco (relating to Half-Blood Prince. ...And not in a shippy way. *g*)
People: Keira Knightley, Audrey Hepburn, Zooey Deschanel, Jake Gyllenhaal, Famke Janseen/Hugh Jackman, Morten Harket (lead singer of A-ha)
Uh, if any daring soul wants to use these, you don't have to credit. That doesn't mean you can steal them, though. :p As always, resources are here.
