What is defined as commercial use?
Other than the obvious, in which you sell the work in question, commercial use can be a gray area. For example, if you put a photo on a website, and the website runs Adsense ads or sells products, it can be argued that that is commercial use of the photo. But if you put a photo on a website that is not commercial in any way, but that website links to another website that you also own that is commercial, it gets a bit more tricky. If there is any doubt at all, why not just consider looking for content that permits commercial use. That way, there will be no issues. 🙂 At the moment, Creative Commons is conducting a study into what constitutes “non commercial use”. It is scheduled to be completed by early 2009. Do I need to register with Creative Commons to use their licenses? No you do not. Creative Commons does not keep track of works using its licenses. How can I use these licenses? There is a great guide on their site on how you can actually license your content using theor licenses.
