Life happens.....if nothing else find a way to get names, dates, and maybe places on the photos. Write lightly with color that shows up on the back of those old grey photo card boards. My father and grandmother wrote on many of our photos (for which I am grateful) but they used red ink, sometimes on the front of the photo. If making a note on the back of regular photographs do not press hard, it makes ridges on the front. If possible do not cut off those cardboard frames and do not take the name and place of the photographer off. If the names and towns are left intact sometimes one can figure out who is in the picture when they know where family members lived. I have 3 of those...only knew who it was by the name of the town. We have 30 years in genealogy. Good luck.
