Family photos (or videos or films) are never valued but are always divided in kind. The method I use (and one that no one has ever complained about) is to segregate all pictures into one group and then designate one of the parties to divide the photos into two "equal" groupings of photos. The other spouse then has the opportunity to choose whichever "equal" group he or she prefers. After such a choice is made each party may go through the otherís partyís half and have the opportunity to reproduce any picture in the otherís possession, at the cost of the party choosing to make the copy.
