Im not sure about the highlights thing but with the photos you will have to go to his profile and go thru his pictures, find ones with you in them and underneath the photo on the right side theres a thing that says report photo, click that, i think you can write in why you are reporting the photo so think of something like you dont want pictures of you on his facebook as you didnt give him permission and no longer get along with him so for your own privcay and safety you want them removed. Good luck
