The thing about family photos that's most important is to have THE NAMES of everyone in the photo, not "mom" or "lucy"... actual full names, so that someone in a generation or two can actually understand who is who. My wife's family had that... but then the photos were ripped out of the album, and all context was lost. 8(
As much as possible, I've got every face tagged in my photos so sproutlet has something useful when the time comes.
