Taking Pictures - How many can you take?

I know it is stereotypical to say Japanese people take a lot of pictures, but, I do confess that in my family picture taking is just a part of our lives.  Every family event, or sports event involving family, the cameras come out.  We always joke that we take pictures of every possible combination of our family at our parties.  I have noticed though, that there are some family members, who shall remain nameless, that take the most pictures and ask us to pose and take a zillion pictures, but quite honestly, I never see their pictures.  I am not sure why they feel the need to take all those pictures they never show anyone.  I will say, one day, I did laugh out loud, when I received an email from one of the "picture takers"  of pictures from about two years ago and those are the only pictures I ever did see,  just that one time.  Oh well, I bet every family has one of those "picture takers".
