You'll have to let us know what you are trying to do if you want a proper answer.
Off the top of my head:
1) Google images, with planets, mars, saturn, titan etc. gives a lot of images.
2) The Terragen site or Vue or WetCanvas probably have some fantasy and some real planet images. Some breathtaking.
3) Programs like, Bryce, Terragen... allow you to model planets and get exactly what you want. Also some of those game development graphics programs.
4) The jpl site has some images, actual photo's and artist's impressions both.
5) Depending on where you are, you might be able to borrow a good telescope and actually look at the moons of the gas giants, in kinda real time.
