I'd like to use some public domain photos as node images on RGL. I'm not entirely sure how to do this within the "node image" system - the OpenGuides templates automatically put the little "(c)" copyright symbol in front of the name of the person who took the photo. I found a public domain licence on the Creative Commons site: http://creativecommons.org/licenses/publicdomain/
but I don't really understand this sort of thing so I thought I'd ask for help here. What should I put in the little boxes on the OpenGuides edit form in this situation?
Kake P.S. Yes, they are definitely public domain; a friend of mine took them.
