What is Open Access?
"Open Access stands for unrestricted access and unrestricted reuse." (this definition is from PLoS (Public Library of Science), an open-access peer-reviewed journal). Open access doesn't mean that the copyright holder has given up their copyright -- items with no copyright holder or whose copyright has expired are in the "public domain."
Creative Commons is on a mission to make open access content more accessible and understandable by providing a set of licenses that can be used for open access content. The copyright holder gets to choose the license they want to apply to their own work.
Use this handy chart to understand the different permissions allowed by each Creative Commons license. For your infographic project, you're going to want to be able to modify & adapt images (put those new Photoshop skills to work!):
