Set All First Images As Featured

still works

It simply didn't recognize any images in any of the posts, and so didn't work. :(

Didn't see the images in the posts

IT works on 5.0.3

<p>Preload Featured Images automatically in posts to increase the PageSpeed Score.</p>
<p>This plugin is a “must-have” for websites using themes that display the Featured Image automatically at the top in single post pages.</p>
<h3>Why was this plugin created?</h3>
<p>Suppose your theme displays the Featured Image at the top in posts automatically. In that case, the chances that the image is the <strong>LCP (Largest Contentful Paint)</strong> are very high, so the PageSpeed tool will highly recommend you to preload it.</p>
<p>Are you getting the following recommendation when testing the PageSpeed score of a single post: <strong>“Preload Largest Contentful Paint image”</strong>? Then this plugin will help you!</p>
<h3>How it works?</h3>
<p>Go to the <strong>Settings > Preload Featured Images</strong> page and choose the image size used by your theme to make sure the right image size is preloaded.</p>
<h3>Compatible Themes</h3>
<p>The plugin supports all themes, but it’s very important to choose the right Image Size on the settings page.</p>
<p>If you are not sure which is the image size used by your theme, simply get in touch with your theme’s developer and they will be able to help you with that.</p>
<p>If you’re using one of the following popular themes, then the plugin will automatically pick the right Image Size, so you don’t have to configure anything:</p>
