Various Family Photos, with scan of the back side of the photo, where usually mum wrote some details. These were scanned as backup when leaving Seattle, in case of non-arrival in Sydney. I do have them in good condition.
Older slides have no date on them; newer ones do have the date, at least. When dates are available, the filename format is XXyymmSnnn.jpg, where XX is a 2 letter code designating film maker and type (e.g. kk would be Kodak, and Kodachrome film), then 2 digits for year, 2 digits for month (film processed, not necessarily shot), S is a letter to allow for multiple yymm values, and nnn is the sequence number on the film.
