BTW, doesn't an online magazine fall in the same concept of editorial usage that requires credit to the agency and photographer?
Does anything require editorial to credit the agency and photographer or is that just what some agency licenses demand?

If it's not listed, you'll never know, which is kind of circular, since you can't tell who sold it, to see if the contract requires credit to the photographer. Confused?
