Choose one image with its owner
A small start is kinder to the project than an entire box spread across a table. Invite the owner to choose a picture they feel comfortable discussing, including one from a recent day if that is more enjoyable. Do not assume a childhood or wedding photograph is welcome simply because it is in the collection. Leave the original in its usual safe place where possible and work with a copy for notes or display.
Ask what belongs beside it
A useful caption might identify the people, place and occasion, but those details are not a test. Start with what the person wants to say. A remembered sound, a familiar routine or the reason the photograph was kept may matter more than an exact date. Write a draft in their own language and read it back. Let them decide whether that wording feels right and whether anything should stay private.
Keep uncertainty visible
If a date is approximate, say so. If a name is uncertain, keep that uncertainty rather than filling in a plausible answer. Note who supplied the memory and when the conversation happened. Different relatives may remember an event differently; you can keep both accounts as attributed recollections without forcing one version to become the official family story. A short honest note is more useful than a polished caption that conceals where its details came from.
Agree the next use separately
Permission to talk is not automatically permission to post online, send to a group or include in a gift book. Ask what the person is happy to have kept and who may see it. Take care with details about other people who appear in the image or story. You can make a private note without making a public archive. If you plan to share a copy, show the proposed caption and audience first.
Choose a manageable home for the copy
Put the image and its agreed note together in a folder or album that fits your actual prints. If a valuable or fragile original needs treatment, get appropriate preservation advice rather than experimenting with adhesives or cleaning products. The ordinary project here is to keep context alongside a usable copy. Finish one page, label it clearly and decide whether anyone wants to repeat the process another day.
