Recover photos from iPhone with broken screen

I'm trying to recover my photos from my old iPhone which has a nonworking, broken screen. When I connect it to my computer it tells me to say i trust this computer through my iPhone, which i am unable to do because of the screen being broken. My phone still works, it lights up and makes noises, just the screen is wrecked and wont let me unlock it or select anything. Any ideas on how to get my photos back?
