# CAROUSEL FIX - QUICK START

## What Was Fixed
Carousel images showing 404 errors (images loaded without file extensions like `pics/ai1` instead of `pics/ai1.jpg`)

## What You Need to Upload

### NEW FILE
```
📁 carousel_image_handler.php (153 lines, ~4 KB)
   └─ NEW: Carousel-specific image finder
   └─ Purpose: Finds images by ID and returns actual path
```

### MODIFIED FILE
```
📁 js/image_loader.js (updated)
   └─ UPDATED: Added carousel detection & routing
   └─ Purpose: Detects carousel images and uses handler
```

## How to Deploy (3 Steps)

### Step 1: Upload carousel_image_handler.php
- Upload new file: `carousel_image_handler.php` to `/emporio/` directory
- Set permissions: 644

### Step 2: Replace js/image_loader.js  
- Upload updated: `js/image_loader.js` to `/emporio/js/` directory
- Set permissions: 644
- Replaces existing file completely

### Step 3: Test in Browser
- Open homepage in new private window
- Press F12 → Console
- Look for: `[Carousel]` messages
- Images should appear (not gray boxes)

## How It Works

```
User sees carousel in broken state:
    ↓
Browser tries: <img src="pics/ai1">
    ↓
404 Error (no extension!)
    ↓
image_loader.js detects: "carousel image without extension"
    ↓
Calls: carousel_image_handler.php?action=find&id=ai1
    ↓
Handler finds: pics/ai1-xxxxx.jpg
    ↓
Updates: img.src = "pics/ai1-xxxxx.jpg"
    ↓
Image loads successfully ✓
```

## Testing Quick Checklist

- [ ] Carousel images visible (not gray)
- [ ] No "Failed to load resource: pics/ai1" errors
- [ ] Console shows "[Carousel] Found image:" messages
- [ ] Carousel works (arrows/slides)
- [ ] Other images still load

## If It Doesn't Work

### Check 1: Files Uploaded?
```
Via FTP, verify these exist:
✓ /emporio/carousel_image_handler.php
✓ /emporio/js/image_loader.js
```

### Check 2: Permissions Set?
```
Both files should have permissions: 644
```

### Check 3: Clear Cache
```
Hard refresh: Ctrl+F5 (Windows) or Cmd+Shift+R (Mac)
Or use private/incognito window
```

### Check 4: Test Handler Directly
```
In browser, visit:
https://yoursite.com/emporio/carousel_image_handler.php?action=find&id=ai1

Should return:
{"success": true, "path": "pics/ai1-xxxxx.jpg", "error": null}
```

### Check 5: View Error Log
```
cPanel → Logs → error_log
Look for PHP errors or permission issues
```

## Files Reference

### carousel_image_handler.php (NEW)
- Size: ~4 KB (153 lines)
- Type: PHP (version 5.6+)
- Purpose: Find carousel images by ID
- Functions:
  - `action=find&id=XXX` → Returns image path

### Support Files (UNCHANGED)

- header.php ✓ Already includes image_loader.js
- .htaccess ✓ Already configured
- CSS files ✓ All in place

## Success Indicators

### Console Messages (Good)
```
✓ [Carousel] Detected carousel image: ai1
✓ [Carousel] Found image: pics/ai1-xxxxx.jpg
✓ Image loaded: pics/ai1-xxxxx.jpg
```

### Console Errors (Bad - means not working)
```
✗ Failed to load resource: pics/ai1
✗ Carousel Image not found
✗ Handler error
```

## Performance

- First image load: ~2-3 seconds (handler fallback)
- Subsequent loads: Instant (browser cache)
- Network: One extra request per carousel image
- Server: Minimal overhead (lightweight PHP)
