Guys, I need your help! Whoever is of the artsy persuasion or might be able to help me out... I'm looking for high-res SPN stills and shots, both in general and specifically right now of Jensen/Dean preferably later season with as much face/in portrait as possible. I do really well sussing out video material I need, but I really have no clue about still images. I have a few popular images in mind, but I'm not sure where to find high quality sources, and I'm open to all suggestions. You can comment with links for communities or collections, direct-to-source URLs or dropbox me stuff from your own storage if you can find images that might fit the bill.
Thank you, thank you, thank you in advance.
