Digital history

I have not used my camera to make any images today, but I have received variously; 40 digital images from a trip to India in 1999; 23 digital images from a trip to Ireland in 1997, and one image from a visitor to my home in Greece on this day in 2017. Each of which has been edited by me at home today to ensure that they all comply with blip date and copyright rules.
I imagine you can work out for yourselves which is which.
