<h4>Community Acceleration Network (Opt-In Feature)</h4>
Important: This is a peer-to-peer (P2P) network, NOT a traditional CDN like Cloudflare or AWS. Your site will both receive AND serve cached resources to other community members.
When enabled, your site can participate in the VN-Nexus Community Network to share cached resources and help accelerate loading for other community members.
Privacy & Transparency: 
* 100% anonymous participation 
* No personal data collected 
* Requires explicit user opt-in 
* Can be disabled anytime 
* Check your hosting provider’s Terms of Service before enabling (some hosts restrict P2P)
How it works: 
* Your site announces cached resource availability to the network 
* Other sites in the network can request these resources (typically 1-5MB/day for small sites, 10-20MB/day for medium traffic sites) 
* Everyone benefits from faster loading speeds 
* All communication is encrypted and anonymous
Note: This is an experimental community-driven project and not a replacement for commercial CDN services.

This plugin is a “must-have” for websites using themes that display the Featured Image automatically at the top in single post pages.
<h3>Why was this plugin created?</h3>
Suppose your theme displays the Featured Image at the top in posts automatically. In that case, the chances that the image is the LCP (Largest Contentful Paint) are very high, so the PageSpeed tool will highly recommend you to preload it.
Are you getting the following recommendation when testing the PageSpeed score of a single post: “Preload Largest Contentful Paint image”? Then this plugin will help you!
<h3>How it works?</h3>
Go to the Settings > Preload Featured Images page and choose the image size used by your theme to make sure the right image size is preloaded.
<h3>Compatible Themes</h3>
The plugin supports all themes, but it’s very important to choose the right Image Size on the settings page.
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.
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:
