You're not selfish at all. It is selfish for her to ask you to not have a beautiful, loving support system by your side on one of the most beautiful days of your life. It also gives her an opportunity for introductions with people that will carry you through the rest of your lives. And your children's lives if you're having them. Extended family is critical to have when needed for support in the future should something happen to either one of you. As you said, her parents cannot make the flight. She needs your friends and family. I hope you can convince her if this. Also pictures are amazing to have for your lifetime. I don't have them and don't have answers. There is back story but cannot explain here. Irish Catholic. We don't have many photos at all. It is a regret because now I don't like taking photos either. Use your voice kindly, and hopefully, will listen. If not it is something serious for you to think about.
