As a photographer, I don't want to see my photos being used by people who don't have rights to them or didn't pay for them. In the case of the girls, unless they signed a contract or waiver agreeing not to use the photos personally or to allow others to use them when someone else paid for the photos, one can assume the girl will use any and all photos of herself if she's going indie or working with multiple agencies.
As long as the girl in the photo is the girl who shows up, most guys don't care about who "owns" the photo. However, Discreet Referrals is using a photo of a UK model named Michelle Bond a/k/a Michelle Monaghan as their own girl "Savannah."
