A Note on Copyrighted, Public Domain, and Royalty Free Materials
One fundamental rule in all YOBI Contests is that contest entries may not contain any images, sounds, music, or other material that you either do not own or do not have permission to use. Although it may sound severely limiting, this rule is ultimately for your protection.
We recommend that you take a few moments to familiarize yourself with the differences between Copyrighted, Public Domain, and Royalty Free materials. Please note that just because material is public domain or royalty-free does not mean that it will be available at no cost. Likewise, just because material is available at no cost does not mean that it is either public domain or royalty-free.
Public Domain and Royalty Free material is available on numerous websites. Simply pop these terms into your favorite browser and you will find a list of them.
