Every picture on this site may be used for commercial purposes. Every picture is either a Public Domain picture (which has no limits to its use), or licensed under this Creative Commons License, which MAY require a link or a mention of the photographer.
We file all of our pictures under one of two categories, and every one will show which category it falls under:
Public Domain, of course, has no limits, and can be used for any purpose whatsoever.
Photo’s filed under Free Pictures, are Creative Commons Licensed photo’s. Some photographers don’t require an attribute, and some do. If there is a mention of a photographer and a link to his/her website, that is our way of fulfilling the attribute. And we ask that you do the same.
You can still use any picture found anywhere on this website for free, for any commercial purpose. But if you know who the photographer is, please link to their website and help them get some publicity and recognition for their fine work.
