The important thing to remember about Creative Commons Licences are that you do need to attribute the creator.
Attribution is similar to citation. In attribution you need to mention the author, the source, link to the image and cite the kind of Creative Commons licence the material was released under.
Academic citation styles should also be used in addition to attribution for academic and assignment projects, when defined as part of course requirements.
To help you with making Creative Commons citations there is a handy tool called the Open Attribution Builder: https://www.openwa.org/attrib-builder/
Here is a photo. Following it are some examples of how people might attribute it.
This is a pretty good attribution
by tvol / CC BY
- Title? Title is not noted (it should be) but at least the source is linked.
- Author? "tvol"
- Source? "Photo" - linked to original Flickr page
- License? "CC BY" - linked to license deed
This is an incorrect attribution
Photo: Creative Commons
- Title? Title is not noted.
- Author? Creative Commons is not the author of this photo.
- Source? No link to original photo.
- License? There is no mention of the license, much less a link to the license. "Creative Commons" is an organization.
This is a good attribution for material you modified slightly
- Title, Author, Source, and License are all noted
- Modification? "Desaturated from original"
