Hi there and welcome
What you need to do is install iTunes which you can get for free from my link below
Then connect your phone to the computer, open Ituns, synch and the photos will be put on your computer in your pictures library.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know the results please
