Popular websites using images from other websites with a link-back to source in the credit
<p>I've seen this happen all the time. Hugely popular websites like Buzzfeed, Scoopwhoop and several other use images from other websites and leave a link back to source in the credits. What is the legality or this? So if need an image I can just take it from any website and leave a link to the original source?</p>

<p>Let me show you some examples,</p>

<p><strong>Buzzfeed</strong>:</p>

<p><a href="https://i.stack.imgur.com/Au0XU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Au0XU.png" alt="enter image description here"></a></p>

<ul>
<li><a href="https://www.buzzfeed.com/audreyworboys/employee-company-secret-confession" rel="nofollow noreferrer">https://www.buzzfeed.com/audreyworboys/employee-company-secret-confession</a> - Uses gifs from TV shows and leaves the names of the production houses in the credits.</li>
<li><a href="https://www.buzzfeednews.com/article/laurenstrapagiel/tiktok-egirls" rel="nofollow noreferrer">https://www.buzzfeednews.com/article/laurenstrapagiel/tiktok-egirls</a> - They took images from someones Instagram account, uploaded it to their servers and left a back link in the credits.</li>
</ul>

<p><strong>Scoopwhoop</strong>:</p>

<p><a href="https://i.stack.imgur.com/QaPP2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QaPP2.png" alt="enter image description here"></a></p>

<ul>
<li><p><a href="https://www.scoopwhoop.com/news/trillion-trees-to-make-earth-healthy-again/" rel="nofollow noreferrer">https://www.scoopwhoop.com/news/trillion-trees-to-make-earth-healthy-again/</a> - The last image is taken from National Geographic and re-uploaded to their servers. Again they've linked to Nat Geo article. </p></li>
<li><p><a href="https://www.scoopwhoop.com/news/chennai-man-orders-food-swiggy-tries-to-deliver-from-rajasthan/" rel="nofollow noreferrer">https://www.scoopwhoop.com/news/chennai-man-orders-food-swiggy-tries-to-deliver-from-rajasthan/</a> - Images are taken from news websites with links to the news articles.</p></li>
</ul>

<p>Is this okay to do?</p>

<p><strong>NO</strong>, not in general.</p>

<p>Some websites will grant permission to reuse their images conditioned upon a link-back. In that case it is perfectly legal to accept this offer. Some web sites use images released by their authors under a CC or other free license, which can therefore be used by anyone, with or without a link back. Some web sites use images which are, for one reason or another, in the public domain, so copyright simply does not apply.</p>

<p>But when none of these conditions apply, such images may not be reused, with or without a link-back, unless the re-user asks for <strong>and gets</strong> permission from the copyright holder to use them. A link-back is <strong>not</strong> a substitute for permission. It may be that the examples you mention are cases where the re-user did ask for and get permission. Or they may be cases of infringement, where the copyright holder has not (yet) chosen to sue. There is no way to be sure.</p>
