In recent years, I've increasingly been asked to work on/comment on drafts of various marketing materials for my school (brochures, websites, videos etc). One question that often comes up - and I don't know if there's an established etiquette for this or not - is the boundaries of appropriate use of images of visiting professors in these materials, particularly when these visitors are permanently attached to another school.
I've not had a problem with including pictures of people who have visited to give presentations at conferences etc, because it's usually clear from the context of the photograph that they are presenting a paper, or sitting in the audience at a conference, or other conference-related function (eg lunch or dinner). What I'm more confused about is the extent to which you could show a picture of someone visiting as a professor, say, teaching in a classroom, advising students in his/her office, sitting in a faculty meeting etc.
Is it misleading to show visiting professors in this context? And are their home schools within their rights to complain if a visitor is shown in the brochure of another school? Do any schools have policies on this?
