Right...I don't know how frequent of a use-case that is. I know I certainly take advantage of it for my non-profit company. But first of all, I think the percentage of people who want to copy a photo as opposed to just looking/commenting on is relatively small. And the small slice of users who do want to copy a photo, a good percentage of them either don't care about honoring CC or feel that they don't need to worry about it (i.e. they want a photo just to use as their wallpaper).
