I post once per week at capspiration which is fun so by next month I may also start posting one favorite fandom screen cap/picture here a few times a week, mainly for my own amusement.
If I do ever make a zip file of any screencaps I'll cross post to cap_it.
I recommend screencapped, grande_caps, fading_tomorrow, homeofthenutty, cap_it & thepicturepool for all your fandom screen cap needs.
P.S. A few days later, I changed my mind about part of that statement!
