I think it might be a good idea to have the ability to add a year to headshots.

That way when one is looking at a headshot one can know when that headshot was taken.

Let's say that one had done a headshot for someone 3 years ago. So when one looks at the headshot, perhaps when one hovers the cursor over it the year would be displayed or the other way would be to right click it and the year would be displayed that way, one would know that that headshot was taken in 2015.

So when updating headshots one can see that it's 3 years old and if one wants can go and see if they can find a newer headshot.

Usually years are known, such as when at a premiere or a public appearance.

If a year for the photo is not known, one can enter a estimate. Such as an older star and it appears like the photo was from the 1940's. One can enter that estimate instead of a documented year.

Now I don't know if this should be available via trading headshots or something to be kept local. But I could see where having the ability to see what year a photo is from someone else's update could be useful for later updating.
