* Uses the standard WordPress posts table (like revisions) 
* Uses a custom post status (and therefore works for any post type) 
* Easy snapshot management meta box 
* Create Snapshots comfortably in the publish post box 
* Choose which post types you want to enable the snapshots feature for

NOTE: The use of a custom post status in WordPress is still in beta. The developers of this plugin are in no possible case responsible for any data loss. 
If you want to be sure nothing happens, backup your database on a regular basis. You should do it anyway.

Post Snapshots

Everything works as expected and I did not hear any compaints yet.

On our live website it has been working great since two months now

Capture snapshots of any website using the <a href="https://cloudinary.com/console/addons#url2png" rel="nofollow ugc">Cloudinary URL2PNG add-on</a>.
<h4>Use</h4>
Add link to the site you’d like to create a snapshot of, by using the <code>[cloud2png]</code> shortcode, eg:
<pre><code>[cloud2png url="https://wordpress.org"]
</code></pre>
Customize the snapshots
Using the Cloud2PNG Customizer you can change the size and border of the snapshots.
Shortcode parameters
You can override the Cloud2PNG Customizer using the shortcode parameters, they are (with defaults):
<ul>
<li>url=home_url( ‘/’ )</li>
<li>width=430</li>
<li>height=225</li>
<li>border_width=0</li>
<li>border_radius=0</li>
<li>
border_color=#000000
[cloud2png url=”https://wordpress.org” width=”300″ height=”400″ border_width=”5″]
</li>
</ul>
Adding Cloud2PNG to a theme
Using <a href="https://developer.wordpress.org/reference/functions/do_shortcode/" rel="nofollow ugc">do_shortcode()</a>, you can add Cloud2PNG to a theme:
<pre><code>echo do_shortcode( 'url="https://wordpress.org" width="300" height="400" border_width="5' );
</code></pre>
or using the <a href="https://developer.wordpress.org/reference/hooks/shortcode_atts_shortcode/" rel="nofollow ugc">shortcode_atts_{$shortcode}</a> filter:
<pre><code>add_filter ('shortcode_atts_cloud2png', 'add_url', 10, 3);
function add_url ($out, $pairs, $atts ) {
 $out['url'] = 'https://soderlind.no';
 return $out;
}
</code></pre>
<h3>Sidenote</h3>
I code for fun, and I code to learn. I’ve tried to do this plugin using OOP at my best effort. There will be couplings that could be looser and not everything is DRY. I will update the plugin as I learn more and I will fix <a href="https://github.com/soderlind/cloud2png/issues/new" rel="nofollow ugc">issues that are reported</a>.
I’m following the <a href="https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards" rel="nofollow ugc">WordPress Coding Standards</a> with one exception, I’m using the <a href="http://www.php-fig.org/psr/psr-4/" rel="nofollow ugc">PSR-4 autoloader</a> and I’ve disabled the following rules:
<pre><code><rule ref="WordPress-Core">
 <exclude name="Generic.Files.LowercasedFilename" />
 <exclude name="WordPress.Files.FileName" />
 <exclude name="WordPress.Files.FileName.UnderscoresNotAllowed" />
</rule>
</code></pre>
