How do I give each athlete their own gallery?
Sort the album by person, then share each person's set as its own link. The family opens a gallery containing only their athlete instead of searching a squad folder. For a club, that means one link per player handed over in a single message rather than a shared drive nobody opens.
Why it sells better than one big folder
A parent will scroll a few dozen photos looking for their child and then give up. A gallery that contains only their child is browsed to the end. The difference between those two experiences is most of the difference between a gallery people look at and one they buy from.
What the club gets
One message containing a link per player, ready to forward. The club looks organised, and you did not do any extra work to make that true.
In SnapFlow
Each recognised person's frames become a shareable gallery automatically, so the per-athlete links are a by-product of sorting rather than a separate task.
