tracking down company photos

Lately I have been trying to find any pictures that might have been taken of the 121st Infantry Regiment( 2nd Battalion/Company H) but have not had much luck with the main search such as the Archive site.

My first question: is it reasonable to assume such a photo was taken and is even out there to find? Also, are there some sites that I might be unaware of, or are things simply not on the internet?

 

Usually when a unit finished up training or was wrapping up training in the US they had pictures taken either individually or in company size groups. The local post photographer may be able to help in locating them. After units deployed overseas I don't believe they had time for that.
