I sometimes add photos taken by other people (with permission) to my iNat observations where I am certain I can verify location etc., but there is no way to update photo copyright attribution to anyone other than the account holder. In addition to updating type of licence, it would be great to be able to edit image copyright holder too.
Maybe a lifetime of being a part-time photographer makes me pedantic, but given the likely use of good images with appropriate licence elsewhere, it is important that correct attribution is given, and I don’t want to miss out on being able to add key observations from people who do not use iNat themselves.
