I read the link, and that really seems to be about too many pictures of just one person on display, especially when the person is the only one in nearly every picture.
I don't have many pictures on display in my home because I don't have many good family pics yet (I think there are a grand total of two of all four of us). I like looking at family pics and think what you describe is fine as long as it doesn't feel cluttered. In fact, we were taught to specifically include photos of ourselves with our families in our workspaces to help connect with others, and I find that even my family doctor and eye doctor do this in the exam rooms. At least where I'm from, it's actually a connection point, not narcissism.
