If you're curious what images Curiosity is currently returning from Mars, you can always check the raw stream of pictures here: http://mars.jpl.nasa.gov/msl/multimedia/raw/.  They are organized by camera.

I found out about this by reading the "Ask Me Anything" thread by Curiosity Engineers and Scientists on Reddit: http://www.reddit.com/r/IAmA/comments/1jd005/we_are_engineers_and_scientists_on_the_mars/
