The author of the post is in Sweden, not the US.
As weird as it sounds, profile photos are prominent features of resumes in many European countries. It shocked me when I first started hiring in our EU offices, but that's just the way it is. I was surprised because we've often been told so many different ways that Europe is ahead of the US in matters of discrimination, but then I got there and resumes were full of profile pictures and even discussion about their marital status. I had our recruiter over there start erasing these things from resumes and they thought I was crazy.
