Creative Commons is an open licensing scheme in which creators retain the rights to their own work but grant a licence to others to copy and distribute it in a certain manner- without the need to seek permission or pay royalties. There are several types of licences, some only allow material to be used as is, whilst others allow users to modify the material for their own needs or to use it commercially.
The six main licences:
Understanding Creative Commons licences conditions:
Attribution. You must attribute the material in the way the author requests. If you want to use the work without attributing the author / creator or for endorsement purposes, you must get permission first.
NonCommercial. You can copy, distribute, display, perform, and modify the work for any purpose as long as it is not commercially unless you get permission first.
ShareAlike. You can copy, distribute, display, perform, and modify the work, as long as you distribute any modified work under the same terms / Creative Commons licence. If you want to distribute modified works under other terms, then you must get permission first.
NoDerivatives. You copy, distribute, display and perform only original copies of the work. You cannot modify the work unless you get permission first.
