>there's no useful information in a photo
There's lots of useful information in a photo.
A talented HR/CEO can size up a lot of things from it, even from the way the candidate is dressed in the photo.
"Hmm, too old, too quirky looking, doesn't look a good fit for our culture, fucking hipster I hate them, too slopilly dressed don't like working with such guys" etc.
I'd wager half of the observations of this "talented HR/CEO" are illegal.
I am surprised that a CEO publicly declares photos to be useful. A photo is clearly bullshit - there's no useful information in a photo (unless it's "here I am accepting $PRESTIGOUS_AWARD last year") - and it raise risk of discrimination claims.
