The professor asks this of every student. It's 2 points on an introductory assignment worth 10. Does anyone think this is bizarre? I'm against it to the point that I think it should not be allowed by the university.
addendum
It's an online class, by the way. A Senior Communications class is required that most have taken by now. Within that communications class it is required to upload a photo of yourself to the online university system which all classes can see, like in class rosters and private messaging. The professor also asked us to call him (it's explicitly advised at my university not to give your professor your phone number). What really annoyed me was when he then asked permission to share our email among the class. The class already has a messaging system and it can be tied into the university email. This instructor was too pathetic for me, so I dropped the course within a few days.
addendum 2
USA school. top 50 USNews. After seeing these comments I actually find them helpful, because the only reasons I see are to learn the students name, but in this case the professor already has photos of a strong majority of the students. What I'm getting at is the professor is really showing some incompetence and its annoying to a significant extent.
