Preload LCP Image

Description

This plugin will add the ability to preload the largest contentful paint (LCP) Image on an individual page or post. This is designed to remove the “Preload the image used by the LCP element in order to improve your LCP time” warning that Google’s Pagespeed Insights sometimes serves.

For Support

I offer support in two places:-

On Github

This project is now on github, you can view the repository here. There are other versions, but this is the one I’ve put up, so where all the developmental will be tracked.

Installation

  1. Upload the plugin to the /wp-content/plugins/ directory or use the Add New feature
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Go to any post and page and specify the LCP Image for that page.

Should you wish to use this plugin for custom post types, go to Settings > Preload LCP Image. By default it appears on posts and pages although you can set it to appear on any custom post type on this page.

Plugin working as described, really like that you added “fetchpriority high” I do have a suggestion for some future update though: I have a large site with nearly 1000 posts, would love if the plugin could automatically add Preload to post featured images, or possible by Class Name, in my instance that would be: class=”post-featured-image” This would save users with large sites from having to updated hundreds if not thousands of posts, Thanks for listening and good luck with Preload LCP Image, Good Plugin!
