+# Image Optimization Report
+
+**Agent:** performance-optimizer
+**Date:** 2026-03-21
+**Project:** WorkRoot IT Solutions (workroot.in)
+
+---
+
+## Summary
+
+The project had a solid image optimization foundation already in place. This audit identified and implemented targeted improvements to maximize loading performance and Core Web Vitals scores.
+
+---
+
+## Asset Inventory
+
+| File | Size | Format | Location |
+|------|------|--------|----------|
+| `favicon.svg` | 410 B | SVG | `/public/` |
+| `apple-touch-icon.png` | 495 B | PNG | `/public/` |
+| `logo.png` | 1.9 KB | PNG | `/public/` |
+| `og-image.jpg` | 3.6 KB | JPEG | `/public/` |
+| `images/blog/ai-business.jpg` | ~1 KB | JPEG | `/public/images/blog/` |
+| `images/blog/astro-intro.jpg` | ~1 KB | JPEG | `/public/images/blog/` |
+| `images/blog/cloud-migration.jpg` | ~1 KB | JPEG | `/public/images/blog/` |
+
+**Total local image size:** ~8.4 KB (already minimal)
+
+**Remote images via Unsplash CDN:** All portfolio thumbnails, gallery images, and team member photos are served from `images.unsplash.com` with optimized query parameters (`auto=format&q=75`).
+
+---
+
+## Pre-Existing Optimizations (Already in Place)
+
+These were already implemented before this audit:
+
+- **Sharp image service** configured in `astro.config.mjs` for WebP conversion
+- **`OptimizedImage.astro`** component with srcset, lazy loading, aspect ratio preservation
+- **`LazyImage.astro`** component with fade-in animation and reduced-motion support
+- **`dns-prefetch` + `preconnect`** for `images.unsplash.com` in `BaseLayout.astro`
+- **`loading="lazy"` + `decoding="async"`** on all below-fold images
+- **`loading="eager"` + `fetchpriority="high"`** on first portfolio thumbnail (LCP candidate)
+- **Explicit `width`/`height` attributes** on all images to prevent CLS
+- **Unsplash `auto=format&q=75`** parameters for automatic WebP delivery and compression
+- **HTML compression** via `compressHTML: true` in Astro config
+- **Inline stylesheets** for small CSS to reduce HTTP requests
+- **Hover-based prefetch** strategy for faster page transitions
+- **`max-image-preview:large`** robots meta tag for richer search results
+
+---
+
+## Changes Made in This Audit
+
+### 1. `astro.config.mjs` — Remote Image Domain Configuration
+
+**Before:**
+```js
+domains: [],
+remotePatterns: [],
+```
+
+**After:**
+```js
+domains: ['images.unsplash.com'],
+remotePatterns: [
+  { protocol: 'https', hostname: 'images.unsplash.com' },
+],
+```
+
+**Impact:** Enables Astro's image optimization pipeline to process Unsplash images when using the `<Image>` component, allowing future use of Astro's built-in image optimization for remote sources.
+
+---
+
+### 2. `src/pages/about.astro` — Hero Image Priority
+
+**Change:** The main "team collaborating" hero image changed from `loading="lazy"` to `loading="eager"` with `fetchpriority="high"`.
+
+**Why:** This image is visible above the fold on the About page and is a strong LCP candidate. Loading it eagerly with high priority ensures faster Largest Contentful Paint.
+
+---
+
+### 3. `src/pages/about.astro` — Team Member Images Priority
+
+**Change:** First team member image now uses `loading="eager"` + `fetchpriority="high"`. All others remain `loading="lazy"` + `fetchpriority="auto"`.
+
+**Why:** The first team card is often in the initial viewport on larger screens. Eager loading the first card while keeping others lazy balances fast initial render with bandwidth efficiency.
+
+---
+
+### 4. `src/pages/portfolio.astro` — All-Projects Grid `fetchpriority`
+
+**Change:** Added `fetchpriority="low"` to the smaller "all projects" grid thumbnails (these are below the featured section).
+
+**Why:** These images are well below the fold. Explicitly marking them as low priority prevents them from competing with above-fold resources during the initial page load critical path.
+
+---
+
+### 5. `src/styles/global.css` — Global Image Base Rules
+
+**Added:**
+```css
+img {
+  height: auto;
+  max-width: 100%;
+}
+
+img[width][height] {
+  aspect-ratio: attr(width) / attr(height);
+}
+```
+
+**Why:** Ensures all images maintain aspect ratio by default, preventing CLS for any `<img>` tags that might not have explicit CSS. The `aspect-ratio` from attributes is the modern CSS approach to CLS prevention.
+
+---
+
+## Loading Strategy Summary
+
+| Page | Image | Strategy | Reason |
+|------|-------|----------|--------|
+| `about.astro` | Team hero image | `eager` + `fetchpriority="high"` | LCP candidate |
+| `about.astro` | First team member | `eager` + `fetchpriority="high"` | Above fold |
+| `about.astro` | Other team members | `lazy` + `fetchpriority="auto"` | Below fold |
+| `portfolio.astro` | First featured thumbnail | `eager` + `fetchpriority="high"` | LCP candidate |
+| `portfolio.astro` | Other featured thumbnails | `lazy` + `fetchpriority="auto"` | Below fold |
+| `portfolio.astro` | All-projects grid | `lazy` + `fetchpriority="low"` | Far below fold |
+| `portfolio.astro` | Modal gallery images | `eager` | Loaded on-demand when modal opens |
+| `blog/index.astro` | Post thumbnails | `lazy` + `decoding="async"` | All below fold |
+| `blog/[slug].astro` | Hero image | `eager` + `fetchpriority="high"` | LCP candidate |
+
+---
+
+## Format & Compression Strategy
+
+| Image Type | Format | Quality | How |
+|-----------|--------|---------|-----|
+| Local JPG/PNG in `src/` | WebP | 80% | Astro Image component |
+| Unsplash remote images | Auto (WebP if supported) | 75% | `auto=format&q=75` query params |
+| OG image (`/og-image.jpg`) | JPEG | — | Pre-optimized static file |
+| Logo (`/logo.png`) | PNG | — | Pre-optimized static file (1.9 KB) |
+| Favicon (`/favicon.svg`) | SVG | — | Vector, inherently scalable |
+
+---
+
+## Core Web Vitals Impact
+
+| Metric | Impact | How |
+|--------|--------|-----|
+| **LCP** | Improved | `fetchpriority="high"` on LCP candidates, `preconnect` for Unsplash |
+| **CLS** | Maintained | Explicit `width`/`height` + `aspect-ratio` CSS prevents layout shift |
+| **INP** | No change | Image loading doesn't block JS interaction |
+| **FCP** | Maintained | Critical resources already loading correctly |
+
+---
+
+## Recommendations for Future Improvements
+
+1. **Replace placeholder blog images** — The three blog images (`ai-business.jpg`, `astro-intro.jpg`, `cloud-migration.jpg`) are ~1 KB placeholder files. Replace with real, high-quality images (800×500px, JPEG/WebP, ~50-100 KB each) for better visual quality.
+
+2. **Self-host critical images** — Consider self-hosting team member photos for the About page instead of relying on Unsplash CDN. This eliminates third-party CDN dependency and gives full control over caching headers.
+
+3. **Add `<picture>` with AVIF** — For local static images, use `<picture>` elements with AVIF as the primary format and WebP as fallback for maximum compression (AVIF is ~50% smaller than WebP for photographic content).
+
+4. **Implement responsive images for OG image** — The current `og-image.jpg` at 3.6 KB is very small and may appear low-quality when shared on social media. Create a proper 1200×630px OG image (ideally ~50 KB after optimization).
+
+5. **Service Worker image caching** — The existing `sw.js` service worker could be extended to cache Unsplash images with a stale-while-revalidate strategy for offline support and faster repeat visits.
