What photos do you keep?
What will these images mean to future generations? Prioritise those older photos.
Focus on photos of specific people and places.
If you have multiple versions of the same scene, pick the best one: the one with the most people looking at the camera, the least blurry, and so on.
Get rid of duplicates. All you need is one original and a high-resolution scan. You can offer extra copies to interested family members.
