<p>Screenshot Generator is a WordPress plugin that takes screenshots of posts for social media etc. when they are updated.<br />
It uses <a href="http://phantomjs.org/" rel="nofollow ugc">PhantomJS</a> to do this.</p>
</p>
<p><em>Why?</em> When developing <a href="http://toptrust.dk" rel="nofollow ugc">Toptrust</a>, I was tired of manually adding images of posts<br />
when sharing on social media. This was especially true for pages that had no featured/thumbnail images.<br />
I wanted screenshots to be taken automatically, and so Screenshot Generator was born.</p>
<h3>Usage</h3>
<p>When you update a post or page, a screenshot is automatically taken in the background.<br />
After a few seconds, the screenshot URL is saved to the post’s meta key <code>_scrgen_screenshot</code>.</p>
<h3>Screenshots on social media</h3>
<p>An <code>og:image</code> and <code>twitter:image:src</code> is automatically added to the meta tags<br />
when viewing the post. These are only added if the post doesn’t have a<br />
thumbnail, in which case the plugin expects the thumbnail to be added by<br />
you or another plugin. You can change this in the plugin settings page.</p>
<h3>Retrieving screenshots manually</h3>
<p>If you want to retrieve the screenshot manually, you can do so inside a post:</p>
<pre><code><img src="<?php echo scrgen_screenshot(); ?>" />
</code></pre>
<h3>Contributing</h3>
<p>Contributions are appreciated and very welcome. You can contribute in the<br />
plugin’s <a href="https://github.com/lassebunk/screenshot-generator" rel="nofollow ugc">GitHub repository</a>.</p>
<h3>Credits</h3>
<p>The screenshot functionality is adapted from Microweber’s<br />
<a href="https://github.com/microweber/screen" rel="nofollow ugc">Screen</a> code.</p>
