Realistic drawings look like photographs

I can't copy any of these photos/paintings so I will have to post the link --->> Photographs

so you can go see these for yourself. They are so life like and he captures the soul in the eyes. It is beyond anything I have ever seen before..
These are drawn by a man named *Paul Cadden*. 

I have a few photos I don't know what to do with

I got these about 15yrs ago and have kept them. I don't know if I should try to get a hold of say the Antiques Road Show and see if they are worth anything. Or maybe a Museum.
I know the one has General Douglas MacArthur in it. It says it on the back. I'm just not sure what war it was from. The pictures make it all so real. I know you see it on TV and all but to see it in pictures is a different thing. So sad. To think about the person that took these and lived it. To smell the smells, how awful.
