i just backed up my old phone through my mac. How can I access my photos to transfer them to my new phone without using my old phone

I had an accident with my old phone, now the phone still works but the screen does not. I bought a new phone and realized i had not backed up the old one, so I am missing a year of photos. I was able to back up my old phone through my macbook, but now I don't know how to get my photos to my new phone without being able to see my old phone because the screen is broken.
