How do I cite an image from wikicommons in my thesis? I want to use some images from the wikicommons in my thesis, some images state that 'Attribution is not legally required', but I understand that if I don't cite an image it's as if I'm claiming it as my own.

Let's say I want to use the google logo: https://commons.wikimedia.org/wiki/File:Google_2015_logo.svg

This is the attribution mentioned:
By Google Inc. [Public domain], via Wikimedia Commons

Do I just put that attribution under the image in the thesis?

Thank you!
Even if its in the public domain its always good to cite where you get your information from, be that data, images, or whatever, even if its public domain
When I use images that are governed by a license (including public domain, and &quot;fair use&quot;) I identify

the source,
the original author/photographer/painter/etc, and
the specific license that governs its reuse.

Using thorough and accurate citations ensures that you've done everything that needed to give proper credit where credit is due.
It also allows the reader to verify that what you cite is really at the source you give, and is licensed for the use to which you put it.
It doesn't hurt to include in the source, links to the actual source, and to the license (say as defined by Wikipedia, or the specific source you used.
