In my opinion the biggest hurdle for any aspiring game designer is artwork. Especially if you plan to release a game for free you usually have no budget for paying artists. One solution are clipart collections. If you do a search on Google you’ll probably find a lot of clipart galleries, some of them even free. There are also a lot of artists which offer some of their works under Creative Commons, but in my opinion the easiest way is to rely on artwork in the public domain, if you need to illustrate your game/adventure/supplement.
While searching for artwork for my upcoming Gears roleplaying game I found the following sources of PD artwork:
And if these three sites aren’t enough, you can check out the Wikipedia Public domain image resources page. If you know any good sources for free artwork, please share the links in the comments below!
Here are some more place you can get art from:

Two good options for anyone with skill in GIMP or PhotoShop:
1. Flickr has a very handy option under Advanced Search that will let you locate photographs that are made available under a Creative Commons license.
2. Deviantart has a number of stock art resources available as well. (Some members of Deviantart also use the Creative Commons license, but I've never been able to find an easy way to search for that.) For those, you need to check the conditions for each artist, to make sure any use complies with their requirements. It is also possible to simply send a message to an artist asking permission, if you see something you would like to use but isn't in the "stock" category or Creative-ly Commons licensed.
I also find the Web Gallery of Art (http://www.wga.hu/) useful. General web searches for "vintage" photographs is also useful — at least in the U.S., anything pre-1927 is generally a good bet to be out of copyright (but keep in mind that depending on the photo, you may have trademark issues).
The Library of Congress has a lot of public domain images available here: http://www.loc.gov/rr/print/catalog.html.
Thank you for the useful resources.
I found some good old fashion SF here for the Rocketship Empires project I was working on:

You read my mind. I was just thinking of this very issue today. I'm a terrible artist yet I really would love to publish some high quality, free PDFs. Thanks for the resource links!

I also have found this useful link
Also, for a small fee, there are great CD clipart collections in the art sections of Barnes and Noble.
I heard that Arthur Rackham was in the public domain, now!
Searching for him in my Google Reader brought up more links:
