UPDATE: the chart was wrong in in more than one way, we took it down. You can still see the original link in the article, but I do not suggest following its advice, you can read more about it here.
There is a lot of confusion surrounding copyright law and when it’s okay or not okay to use photographs that are not your own. Fortunately, Curtis Newbold, AKA The Visual Communications Guy, created this handy flowchart to help you assess when, why, and where you can use certain photographs. If you find yourself frequently questioning the legality (or morality) of resharing an awesome photo you came across on the internet, you may want to bookmark the chart for quick access.
The flowchart (click here for a big version) makes it easy to understand the differences between Copyright, Fair Use, Creative Commons, and Public Domain–four topics which are often the source of great confusion. On the flipside of things, the chart may also be useful to photographers who wonder about their own photographs and the purposed in which others may redistribute them.
