The grudge against Karen the bad nanny has deep roots, I see :D

Okay screen caps are definitely higher quality than the in game pictures, but it's not a huge difference and certainly not worth the trouble if you're not doing it for yourself. I know I enjoy my little routine with my screen captures, even the cropping, but otherwise I wouldn't do it, in-game quality is quite enough.
(Also high res screen caps with beautiful editing won't make me read something if it's boring^^)
