I thought about this too. I am and only child and have no biological children. My stepsons were already 9 and 14 when we got married and they were never close to my parents and neither is my wife.

I will probably make digital copies of the pictures and get rid of most of them. But when I die, I have no allusion that anyone else will care. Honestly, my wife will probably be the last person who cares about my pictures.
