Whether to give credit/attribute or not for pixbay.com images ?
<p>I am making some training videos to teach some concept of computer for commercial purpose means,  I might be sell these videos in future. </p>

<p>In these videos, I have used the images which I have downloaded from pixbay.com</p>

<p>I want to know whether, attribute  or credit has to give for those images which I have used in my video ? </p>

<p>here is the <a href="https://pixabay.com/en/service/terms/#usage" rel="nofollow">link</a> , where they have mentioned the rules which have to follow to use the images. </p>

<p>I have gone through the this link, most of the rules I have understood, 
but still I want expert advice , to know whether I have to give attributes or credits of those images which I have used in videos. ? </p>

<p>Pixabay’s <em>Terms of Service</em> say about <a href="https://pixabay.com/en/service/terms/#usage" rel="nofollow noreferrer">Using Images and Videos</a> (bold emphasis mine):</p>

<blockquote>
  <p>You are free to adapt and use them for commercial purposes <strong>without attributing</strong> the original author or source. </p>
</blockquote>

<p>In the same section they say that the images and videos "are released under <a href="https://creativecommons.org/publicdomain/zero/1.0/deed.en" rel="nofollow noreferrer">Creative Commons CC0</a>". This is Creative Commons’ "Public Domain Dedication", which is a way to release something into the <a href="https://en.wikipedia.org/wiki/Public_domain" rel="nofollow noreferrer">public domain</a>, and for jurisdictions that don’t know the public domain concept, to release it under something that comes as close as possible to this ("to the extent allowed by law").</p>

<p>From this deed follows that you are allowed to do anything with the work (even <a href="https://opensource.stackexchange.com/q/1386/138" title="Open Source SE: May someone else apply a license to CC0 material?">licensing it under some other license</a>), without <em>having</em> to do something (like providing attribution, or even stating that the work is released under CC0). But note that <a href="https://wiki.creativecommons.org/wiki/CC0_FAQ#What_about_other_IP_related_rights.2C_such_as_trademark_and_patent_rights.3F" rel="nofollow noreferrer">trademark and patent rights are not affected</a> by this.</p>

<p>That said, all this is only the case if the original author (or copyright holder) <em>actually</em> released it under CC0 (or into the public domain via some other way). The risk is (like always with such sites) that the person who uploaded the work to Pixabay hadn’t the right to release it under CC0, in which case neither Pixabay nor you have the right to use it as such.</p>
