Attributing CC-licensed works
Whenever you use a Creative Commons item, you must include an attribution. There is no one right way to do this, it depends on the medium and types of material you are using. You need to include the author, title, CC licence and a link to the original. You can either name the CC Licence or download the CC licence button.
The links below give more information and some sample attributions:
