Well, some of us may horde our images. I often don't post during the weekdays, due to lack of time. So may have more than one upload a day on weekends as a result of this. - I tend to let my images ferment as well. Sometimes I'll shelf them, not thinking they're good enough, and then throw them up for the heck of it later on. - Because of this, the notion that a good artist can't upload more than one image for some styles of art isn't always accurate.
