Really, who the hell would doctor pictures for C&B, anyway? If anyone's been on this forum for a decent amount of time, chances are they have a pretty good grasp on detailing in general, and whatever they do will look good. C&B is for sharing your work, compliments are just a side effect...if someone doctors photos, they'll have to do it for every single picture they post, and that eventually becomes very time consuming. I can't see the benefit outweighing the cost of time.
I could put a coat of wax on my car faster than it'd take me to alter a digital photo to make it look better, and I'm sure that stands for most of the guys on here as well.
