I really think it is interesting to remember space missions currently going on, or even past missions, and look them up. I don't go to wikipedia, I only go to NASA. I find the images section, and the Press Images are so few, I look through the thousands of Raw Images. It's really interesting. Sadly, MRO and Galileo don't have either section, they just have "Images".
Ones to see:
Cassini
Mars Rover (Spirit/Opportunity)
Galileo
This image from New Horizons, nice volcanic eruption Io!
