Two copyright for the same image
<p>When an image has different copyright licenses, which one should I follow? 
For example, <a href="https://commons.wikimedia.org/wiki/File:Photo_of_the_Week_-_Seal_pup_at_Back_Bay_National_Wildlife_Refuge,_VA_(5343673024).jpg" rel="nofollow noreferrer">this image</a> is licensed under Creative Commons Attribution 2.0 and in public domain.</p>

<p>Under CC2.0, the author should be attributed while under public domain, the attribution is not required. I don't know why the same image has two conflicting licenses and is it legal to use the image as public domain?</p>

<p>Different jurisdictions may result in different requirements or rights applying to the same work, depending on where any derivative or other usage occurs.</p>

<p>The image is only known to be public domain inside the USA, per USA federal government copyright law which makes all work produced by federal employees in the course of their duties public domain.</p>

<p>It is not necessarily in the public domain outside the USA, and therefore requires other permission there, such as by the CC license.</p>

<p>Thus, the appropriate license, if any, depends on where the work will be used.</p>
