## Description

Noble Vitals is a lightweight, performance-optimized plugin designed to improve 
your Core Web Vitals, specifically LCP (Largest Contentful Paint), and generate 
native image sitemaps.

#### ⚡ LCP Image Optimization

Automatically optimizes your content images to improve LCP scores:
 * Adds `fetchpriority
="high"` to your LCP image(s) * Sets `loading="eager"` for LCP images * Keeps lazy
loading for all other images (configurable) * Uses WordPress’s `wp_content_img_tag`
filter for safe DOM manipulation * Only runs on singular posts/pages and main query

#### 🗺️ Native Image Sitemap

Generates an image sitemap using WordPress’s built-in Sitemaps API:
 * No custom
XML generation – uses core WordPress functionality * Includes featured images from
your posts and pages * Configurable which post types to include * Adds proper Google
image sitemap namespace * Optimized database queries for maximum performance

## Installation

 1. Upload the `noble-vitals` folder to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Go to ‘Noble Vitals WP’ in your admin menu to configure settings.

## FAQ

### Does this plugin use regex to modify images?

No! We use WordPress’s native `wp_content_img_tag` filter introduced in WordPress
5.5, which is the safe and recommended way to modify content images.

### Can I optimize more than one image?

Yes! You can configure how many images to optimize in the plugin settings.

### Is the image sitemap using WordPress’s native API?

Absolutely! We extend `WP_Sitemaps_Provider` and integrate directly with WordPress’s
built-in sitemap system.
