Just a further reply. I'm not alone in unearthing old family photos and wishing to distribute them to family members in the most easily producible form and the most easily readable form. Each of us must be devising/following/modifying ways of doing this with much duplication of others' efforts and with varying degrees of success.
Perhaps readers could describe here what they have done and say how satisfactory the results have been.
We have a common need. Perhaps there is a common solution.
