Good afternoon,

This pull request is a mandatory to work on Magento 2.3 (it seems to work on earlier versions).

This what we meet on error logs :

PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function Magento\Cms\Helper\Wysiwyg\Images::getImageHtmlDeclaration(), 0 passed in /vendor/magento/framework/Interception/Interceptor.php on line 58 and at least 1 expected in /vendor/magento/module-cms/Helper/Wysiwyg/Images.php:200

In the Magento doc :

Before the list of the original method’s arguments, around methods receive a callable that will allow a call to the next method in the chain. When the callable is called, the next plugin or the observed function is called.

When you wrap a method which accepts arguments, **your plugin must also accept those arguments** and you must forward them when you invoke the proceed callable.

http://devdocs.magento.com/guides/v2.0/extension-dev-guide/plugins.html#defining-a-plugin

As a note, Magento's docs said you can also use variadics like
function (...$args)
$proceed(...$args)
when you do not use parameters.
