Makeworthy Media

<p>Disables WordPress from generating image thumbnails when you upload a PDF. This behavior was introduced in WordPress 4.7, so this plugin isn’t needed for any version older than that. Not all web hosts support the ability to generate images from PDFs either, so even if you have 4.7 or newer you might not need this.</p>

<p>Plugin for specifying which thumbnail to use for links liked/shared on Facebook.</p>
<h4>Archive page</h4>
<p>Get a media attached to the first post it can find</p>
<h4>Singular page</h4>
<ul>
<li>Use featured thumbnail when available</li>
<li>Use one of the media attached, when available</li>
<li>Fallbacks to the default image (like a logo which can be specified in settings)</li>
</ul>
<p>Filters are available if you want to shortcircuit the logic or want to add yours.</p>
<p>It just works! If it doesn’t work for you, let me know by creating an issue here – https://github.com/ashfame/facebook-like-thumbnail/issues</p>
