1) So nice to see a new post...I hope you are not too stressed with two job assignments!2) Can't you use your hair length in the picture as a marker of which year it would be? ;-)
These are great!!! I'm sure you had fun coming to NY! That's not far from my neck of the woods :D
Photos are usually encrypted with information on when they were taken and with what device. Flickr always puts this info with an upload, so maybe you could try uploading them there?
