2. This image was part of a Buzzfeed Listacle in 2014
This image was part of a Buzzfeed Listacle in The “author” of the post listed something about this image, but it isn’t enough (and might not even be right). Furthermore, there’s nothing that tells us whether the image is being used with permission.

3. From the same post, the author put in a little more effort
From the same post, the author put in a little more effort. However, it is still not correct. First, imgur is nothing more than a file hosting site.

4. If you click on the link, there is nothing indicating ownership or permission — this does not even explain what we are looking at.

5. Title / Author / Source / License
TASL
The standard for sourcing all images is to include these four things (or as much as you know about all of them).

6. Title / Author / Source / License
In the top example, the “source” is hyperlinked directly to the Flikr image where it is originally hosted.
If you cannot hyperlink, you should write out the source (as done in the bottom example).
"Creative Commons 10th Birthday Celebration San Francisco" / Timothy Vollmer / CC BY 2.0 OR
"Creative Commons 10th Birthday Celebration San Francisco" / Timothy Vollmer / / CC BY 2.0

7. What is the name of the material?
Title
What is the name of the material?
If a title was provided for the material, include it.
Sometimes a title is not provided; in that case, don't worry about it.
The title of this is
Creative Commons 10th Birthday Celebration San Francisco

8. Author: Who created the material?
Name the author or authors of the material in question.
Sometimes, the licensor may want you to give credit to some other entity, like a company or pseudonym (like “tvol,” which is his username).
Timothy Vollmer
You can link
to "tvol" (profile page)
In rare cases, the licensor may not want to be attributed at all.
In all of these cases, just do what they request.

9. Source: Where can I find it?
Since you somehow accessed the material, you know where to find it.
Provide the source of the material so others can, too.
Either hyperlink (ctrl+k) or write out the link:
Since we live in the age of the Internet, this is usually a URL or hyperlink where the material resides.
"Creative Commons 10th Birthday Celebration San Francisco"

10. License: How can I use it?
You are obviously using the material for free thanks to the CC license, so make note of it.
Don't just say the material is Creative Commons, because that says nothing about how the material can be used.
Remember that there are six different CC licenses; which one is the material under?

11. Types of licenses Attribution License
You are allowed to publish the image (even for commercial use) and modify it (e.g. crop, resize, etc) as long as you link back to the author

This license is often compared to “copyleft” free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use.

This license allows for redistribution, commercial and non-commercial, as long as it is passed along unchanged and in whole, with credit to you.

14. Attribution-NonCommercial

The new works must acknowledge the original author and be non-commercial
CC BY-NC
This license lets others remix, tweak and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.

15. Attribution-NonCommercial-ShareAlike
You may remix, tweak and build upon others’ work non-commercially.
Must credit original author and license new creations under the identical terms.
CC BY-NC-SA
This license lets others remix, tweak and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms.

16. Attribution-NonCommercial-NoDerivs License
No commercial use is allowed.
CC BY-NC-ND
This license is the most restrictive of our six main licenses, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.

17. How to search for images with the appropriate license?
Use Google Image Search … but set the license setting to LABELED FOR REUSE
