The Kennedy Space Centre website has lots of pics of both Shuttle and Expendable Launch Vehicle operations, eg Titan, Altas .... but you'll have to navigate your way around. The multimedia section has a few, and there's an archive somewhere going all the way back to project Mercury.
NASAs planned new launch vehicle is called the Crew Exploration Vehicle, or CEV for short. It is to be more of an Apollo style vehicle to be launched atop a shuttle booster(s). Here's a link to the NASA gallery for the CEV.
