There is no standard for attributing open (Creative Commons) licensed content that you reuse.

Best practices advise that you include:

Title,
Author,
Source, and
License (including the name of the license and a link to the license deed)

Examples

Example 1: Online content

Image of cupcakes with Creative Commons logo

This is an ideal attribution for online content...

"Creative Commons 10th Birthday Celebration San Francisco" by tvol is licensed under CC BY 2.0

... because the required elements are all present:

Title? "Creative Commons 10th Birthday Celebration San Francisco"
Author? "tvol" - linked to their profile page
Source? "Creative Commons 10th Birthday Celebration San Francisco" - linked to original Flickr page
License? "CC BY 2.0" - linked to license deed

... because the required elements are all present:

Title? "Eid Mubarak"

KEEP IN MIND:

How you attribute authors of the CC works will depend on many factors, for example: whether you modify the content, if you create a derivative, and if there are multiple sources.

Find out more about attribution on the Creative Commons Wiki.
LangOER's OER Handbook has useful guidelines for how to attribute when using compiled materials from multiple sources (pg. 18), attributing different kinds of media (pg. 19), and attributing content that you have modified (pg. 20).
