OK, so I just posted a big "sexy picspam", and then I realized I have so many James pictures I never posted before,that I could have posted. Let's correct that mistake by posting lots and lots in the same post - there can never be too much James beauty!
The uncredited ones are screenshots/promotional photos of Battlestar Galactica. The uncropped on-set photos are from the Last Days of BSG video, by Dennys Ilic. You can watch it here. And no, I won't bother to crop them all at this point.
