Well, you can creat a custom editorial license, where you specify the value of the digital file depending of the final use:
EX: I am an editorial photographer and I sell images to magazines, newspapers, and the same image can have different prices, depending on the final use:
1 time only
Unlimited use during a 1yr period
Web use only but no printing.
one single image can have different prices, but if you put one price for the editorial use, let's say $50 per image, it can be cheap for a full page of expensive for a small res file published on the web.
I've using another photo service to post my editorial work, and zenfolio for special events the ones that come with a flat rate per event, and not per image.
Hope it helps,
