This plugin adds a section to your Settings menu in the wp-admin section. Through that section you can perform two tasks:
<ul>
<li>A scripted, one-time action updating all of the posts in your blog that do not have a featured image where the script will either try to find a suitable image to use or use one you have provided and configure it for you.</li>
<li>An ongoing, continuous monitoring for posts that do not have a featured image, using the same logic to try and find a suitable featured image and setting that for the post.</li>
</ul>
You can find additional documentation for this plugin on the author’s blog <a href="https://blog.nickleghorn.com/2021/01/25/adding-a-featured-image-to-all-posts-in-wordpress-in-one-easy-click/" title="blog.nickleghorn.com" rel="nofollow ugc">blog.nickleghorn.com</a>
Special thanks to Robert Farago for giving me yet another massive site without any Featured Images to clean up for the impetus to finally make this available.

Sometimes, you run into a situation where you just need to manually run a script. The actual logic might be as simple as generating a csv from a query, or changing a user’s settings, or even just running a single line of SQL. WordPress makes this difficult.
There are many hacky solutions to the problem, but most of them lack security or are too difficult for anyone but a developer to run or just take too long to build. That’s where we come in.
WP Utility Script Runner lets you start with a simple 17 line template, add in your custom code, save to the server, and in minutes you have a secure, fully featured utility, that you can safely run from the WordPress dashboard.
But that’s not all! With a few extra lines of code, your utility can:
<ul>
<li>Accept user input</li>
<li>Accept file input</li>
<li>Run at a future date and time</li>
<li>Run on a recurring schedule</li>
<li>Run large tasks by breaking them up into several smaller tasks, and saving state.</li>
<li>Create reports and other output files</li>
</ul>

WP Utility Script Runner

Create custom scripts and manage them directly from the WordPress Dashboard. Schedule scripts, handle user input, download reports, and more.
