+    └── cover-{200,300,400,600,800,1200}w.webp
+```
+
+**Result**: All 4 existing blog posts have complete optimized image sets with both JPG and WebP variants.
+
+### 2. BlogImage Component Updated ✅
+
+Verified component implementation in `src/app/[locale]/blog/page.tsx`:
+
+```typescript
+function BlogImage({ src, alt }: { src: string; alt: string }) {
+  return (
+    <Image
+      src={src}
+      alt={alt}
+      fill
+      sizes="(max-width: 640px) 350px, (max-width: 768px) 400px, (max-width: 1024px) 550px, 400px"
+      className="object-cover transition-transform duration-700 group-hover:scale-110"
+    />
+  );
+}
+```
+
+**Key Features**:
+- Uses Next.js Image component for automatic optimization
+- Responsive `sizes` attribute matches viewport breakpoints
+- No base64 placeholder (removed)
+- Fill layout for aspect-ratio control
+
+### 3. Base64 Placeholder Removed ✅

+
+**Expected Image Loading**:
+- BlogImage should load ~350px width variant
+- Images: `cover-400w.webp` (closest match)
+- Aspect ratio: 16:9 maintained
+- No layout shift during load
+
+**Verification**:
+- [ ] Open DevTools, set to mobile viewport (375px)
+- [ ] Reload page and check Network tab
+- [ ] Verify correct image sizes loaded
+- [ ] Check no horizontal scrolling
+
+### Tablet Testing (768px width)
+
+**Viewport**: iPad / Medium tablet
+
+**Expected Image Loading**:
+- BlogImage should load ~400px width variant
+- Images: `cover-600w.webp` (closest match)
+- Grid: 2 columns of cards
+- Smooth hover effects
+
+**Verification**:
+- [ ] Set viewport to 768px
+- [ ] Reload and verify image sizes
+- [ ] Check grid layout (2 columns)
+- [ ] Test hover interactions
+
+### Desktop Testing (1440px width)
+
+**Viewport**: Standard desktop
+
+**Expected Image Loading**:
+- BlogImage should load ~400px width variant (3-column grid)
+- Images: `cover-600w.webp` or `cover-800w.webp`
+- Grid: 3 columns of cards
+- Full hover effects and transitions
+
+**Verification**:
+- [ ] Set viewport to 1440px
+- [ ] Reload and verify image sizes
+- [ ] Check grid layout (3 columns)
+- [ ] Test all interactive elements
+
+---
+
+## WebP Format Verification
+
+### Chrome/Edge (WebP Supported)
+
+**Expected**:
+- All images loaded in WebP format
+- File extension: `.webp`
+- Smaller file sizes compared to JPG
+- Network tab shows `image/webp` content type
+
+**Verification Steps**:
+1. [ ] Open Chrome/Edge DevTools
+2. [ ] Navigate to Network tab
+3. [ ] Filter by "Img"
+4. [ ] Reload `/blog` page
+5. [ ] Verify all blog images are `.webp` format
+6. [ ] Check response headers: `content-type: image/webp`
+
+### Safari (WebP Supported - Modern Versions)
+
+**Expected**:
+- WebP images loaded (Safari 14+)
+- Fallback to JPG on older Safari versions
+
+**Verification**:
+- [ ] Test on Safari 14+ (should load WebP)
+- [ ] Verify image quality and loading
+
+---
+
+## Performance Verification
+
+### Lighthouse Audit
+
+**URL**: `http://localhost:3000/blog`
+
+**Metrics to Verify**:
+1. **Performance Score**: Should be ≥90 (maintained or improved)
+2. **LCP (Largest Contentful Paint)**: Should be <2.5s (preferably <2s)
+3. **CLS (Cumulative Layout Shift)**: Should be <0.1
+4. **FCP (First Contentful Paint)**: Should be <1.8s
+
+**Specific Checks**:
+- [ ] No oversized images warning
+- [ ] Properly sized images recommendation (should pass)
+- [ ] Next-gen formats (WebP) used
+- [ ] Image elements have explicit width/height
+
+**Before vs After**:
+- **Before**: Base64 SVG placeholders added ~10.8 KB to HTML
+- **After**: Optimized images loaded on-demand, HTML payload reduced
+
+### Network Waterfall Analysis
+
+**DevTools Network Tab Verification**:
+
+1. [ ] Open Network tab in DevTools
+2. [ ] Navigate to `/blog`
+3. [ ] Analyze image loading:
+   - Images load progressively (not blocking)
+   - Correct sizes loaded for viewport
+   - No duplicate image requests
+   - WebP format used where supported
+   - Reasonable file sizes:
+     - 200w: ~1-3 KB (WebP)
+     - 400w: ~4-6 KB (WebP)
+     - 600w: ~8-12 KB (WebP)
+     - 800w: ~15-20 KB (WebP)
+
+### HTML Payload Size
+
+**Verification**:
+1. [ ] Open DevTools Network tab
+2. [ ] Clear cache and reload `/blog`
+3. [ ] Find the HTML document request
+4. [ ] Verify size is reduced compared to previous implementation
+
+**Expected Reduction**:
+- Base64 SVG removed: ~900 chars per post
+- 12 posts on page: ~10,800 chars = ~10.8 KB reduction
+- This matches previous payload verification
+
+---
+
+## Console Error Check
+
+### Zero Errors Expected
+
+**Pages to Check**:
+1. [ ] `/blog` (German - default)
+2. [ ] `/en/blog` (English)
+3. [ ] `/sr/blog` (Serbian)
+
+**What to Look For**:
+- ❌ No JavaScript errors
+- ❌ No React warnings
+- ❌ No image loading errors (404, CORS, etc.)
+- ❌ No Next.js errors
+- ❌ No console warnings about image optimization
+
+**Common Issues to Watch For**:
+- Missing image files
+- Incorrect image paths
+- CORS issues (should not occur with local images)
+- Next.js Image optimization warnings
+
+---
+
+## Pagination Testing
+
+### Multi-Page Verification
+
+Since there are 8 legacy posts + 4 markdown posts = 12 posts total, all should fit on first page (12 posts per page).
+
+**However, for completeness**:
+1. [ ] Verify pagination shows correctly if >12 posts exist in future
+2. [ ] Test page 2 URL: `/blog?page=2`
+3. [ ] Verify images load correctly on subsequent pages
+4. [ ] Check pagination navigation works
+
+---
+
+## Cross-Browser Testing
+
+### Browsers to Test
+
+1. **Chrome/Edge (Chromium)**:
+   - [ ] WebP support verified
+   - [ ] Responsive images work
+   - [ ] No console errors
+
+2. **Firefox**:
+   - [ ] WebP support verified (Firefox 65+)
+   - [ ] Responsive images work
+   - [ ] No console errors
+
+3. **Safari**:
+   - [ ] WebP support (Safari 14+)
+   - [ ] Responsive images work
+   - [ ] No console errors
+   - [ ] Proper image rendering on macOS/iOS
+
+---
