Shelly,
One way to find a lot of the ships' pictures is to google the ship's name . One good site for a lot of them is
http://www.armed-guard.com/ag24.htmlFrequently the shipyard where they were built and launched will also have photos.
Also, this site has a wealth of information - particularly info about the whole scope of involvement.

BTW was your grandfather ever on the USS Zebulon B. Vance?
