 1 | # FIBS: Featured Image Bulk Set
 2 | 
 3 | This is a plugin designed to do one simple job: programatically add a featured image in WordPress to existing posts.
 4 | 
 5 | I've worked on a couple older WordPress blogs which had hundreds of posts in the old format, where Featured Images wasn't really a 'thing'. Adding a new Featured Image to each one would take days of effort. With this plugin, you can quickly and easily use either the first or last image from within the post to be the new Featured Image.

19 | ## Fair Warning: This Code is Terrible, but Effective
20 | 
21 | No one here is claiming that this is the best or prettiest way of doing this. But it's here, it works, and it's free. 
22 | 
23 | ## How to Use
24 | 
25 | - Download this code and install it in your wp-plugins folder
26 | - Activete the plugin in your WordPress plugin section of the wp-admin panel
27 | - There should be a new section called "FIBS Menu" added to the Settings section. Click that.
28 | - Select your options and hit "save" to start the process. NOTE: this process cannot be stopped once stared.
29 | - NOTE: If you don't click the box at the bottom, you can do a test run of the process to see what the result will be.

 1 | === Featured Image Bulk Set Plugin ===
 2 | Contributors: kc2qcy
 3 | Tags: utilities, featured image
 4 | Requires at least: 4.7
 5 | Tested up to: 6.0
 6 | Stable tag: 1.5.4
 7 | Requires PHP: 7.0

11 | This is a plugin designed to do one simple job: programatically add a featured image in WordPress to existing posts. Either images already in the post, or a default image you can select.
12 | 
13 | == Description ==
14 | 
15 | This plugin adds a section to your Settings menu in the wp-admin section. Through that section you can perform two tasks:
16 | 
17 | * 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.
18 | * 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.
19 | 
20 | You can find additional documentation for this plugin on the author's blog [blog.nickleghorn.com](https://blog.nickleghorn.com/2021/01/25/adding-a-featured-image-to-all-posts-in-wordpress-in-one-easy-click/ "blog.nickleghorn.com")
21 | 
22 | 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.
