Creative Commons refers to a way of assigning a particular type of Copyright licence to your creative work or intellectual property, so that other people can legally reuse it, but within certain guidelines which you specify. As a user you must comply with those guidelines.
All Creative Commons licences require that users of the work attribute the creator. This is also a requirement under Australian copyright law. This means you always have to acknowledge the creator of the CC work you are using, as well as provide any relevant copyright information.
For many users of CC material, attribution is one of the hardest parts of the process. This information guide is designed to help you ensure you are attributing the creator of a CC licensed work in the best possible way. Go to Smart Copying for more CC information.
This video clip from Creative Commons NZ explains in simple format what the different Creative Commons licences mean and how they could be applied.
How to find Creative Commons images?
The images that you find will be fine to use, but you still need to acknowledge who created them and where you got them from.
