awesome. My great-aunt accidentally threw out all of the pictures. My dad's childhood, early pictures of the family when they came to America, all gone. She threw out the wrong bag and stored a grocery bag full of junk instead.
My grandpa on the other side has scanned hundreds and hundreds of pictures of that side of our family, but I have seen very few. I hope he has been annotating them. I assume this required a lot more time than you have, since you are not an 85 year old retired man. I have seen glimpses of the albums, which include stuff like him sitting on a llama as a baby with the Andes in the background, his mean dad taking a selfie in the mirror and glaring, etc.
So far I haven't found any

family resemblances.
There is this one picture of my grandpa and grandma when they were first dating in the 50s, and I swear to god it is a picture of me. He is so awkward and skinny and trying to look suave and smiling nervously, and my grandma looks like a movie star. Based on talking to him and talking to my mom about him, I got basically every personality trait from him, too.
So, yes, definitely try to preserve these however you can. Any method which would allow sharing with family members is ideal.
