Wikipedia:Non-free content proposal Introduction
Wikipedia is founded on the principle that it be a free-content project so that legal issues regarding copyright are avoided or at least minimized. Most Wikipedia Foundation projects do not allow the upload of non-free use images or media. This is because not all legal jurisdictions around the World permit such usage. US copyright law does permit some cases of what is known as 'fair-use' usage of copyrighted material without obtaining prior permission of the copyright holder. As an encyclopedia, Simple English Wikipedia is tasked with providing a free knowledge resource for readers that is freely distributable and modifiable by editors and others regardless of media types used or media types the content is used in. Images often aid understanding of concepts.
