We had a wonderful wedding, sunny day, everything went smoothly

I just received my wedding pic from one of our 3 photographs ( who was also a friend and attended the wedding as a guest / photograph )Pictures are very nice until the part where I see a photoshoot of an other couple ( invited to our wedding and the woman was my bridesmaid ) on the wine yard. I am not talking about 2 pictures, I am talking about 20-30 pictures of them, looking at each other and posing. I am very confused why these people thought our wedding would be the perfect place for them to take pictures ( I know they also have an engagement and a baby on the way ). And I am a little bit upset cause I don’t have picture with my sister for example.I am waiting for the other pictures from other photographs and I don’t know if I should adress it to the couple and the photograph or just let it go … what are your thoughts ?!
