Good point Richard, I will add this disclaimer to the site:FourthWorld wrote: ...and that such media is licensed explicitly for such reuse (GPL, Creative Commons, Public Domain, etc.). Of course you can also contact the creator of the original work to obtain a license to use it.
Similarly, it may be best to avoid trademarked names unless you have explicit permission from the mark owner.
Freely available, external artwork and media may be used as long as it is licensed explicitly for such reuse (GPL, Creative Commons, Public Domain, etc.) The artwork authors should be credited. This applies to sounds and graphics likewise.
If you have any suggestions to make it clearer, I'd be happy to add them. That being said, not everyone is an artist, so using GPL,CC,and public domain assets is encouraged. I highly recommend anyone who needs game assets to check out http://www.opengameart.org which has a ton of game art and sounds under varying licences. Another great site to check out is http://www.openclipart.org which has a huge amount great art that is all in the public domain. If anyone knows of any other similar sites, please share them!
