# Image URL Construction Fix

## Problem
The application was experiencing Next.js image optimization errors due to malformed URLs. The issue was in the construction of CDN URLs where the AWS CDN base URL was being concatenated with image paths without proper slash handling.

### Error Example
```
Invalid src prop (https://d2blq4bj1mzc5m.cloudfront.netdhp/01JX0K2P070QEZ0C0MTR3FHYAV.png)
```

This should have been:
```
https://d2blq4bj1mzc5m.cloudfront.net/dhp/01JX0K2P070QEZ0C0MTR3FHYAV.png
```

## Root Cause
The AWS_CDN_URL constant (`https://d2blq4bj1mzc5m.cloudfront.net`) was being concatenated directly with image paths (e.g., `dhp/01JX0K2P070QEZ0C0MTR3FHYAV.png`) without ensuring proper slash separation.

### Problematic Code Pattern
```tsx
src={`${AWS_CDN_URL}${imagePath}`}  // Missing slash
src={`${AWS_CDN_URL}/${imagePath}`} // Works but not robust for all cases
```

## Solution
Created a centralized utility function `getImageUrl()` in `/utils/imageHelper.ts` that properly handles URL construction with robust slash management.

### Implementation

#### 1. Created Utility Function
```typescript
// utils/imageHelper.ts
export function getImageUrl(imagePath: string): string {
  if (!imagePath) return "";
  
  const cdnUrl = AWS_CDN_URL.endsWith('/') ? AWS_CDN_URL.slice(0, -1) : AWS_CDN_URL;
  const path = imagePath.startsWith('/') ? imagePath : `/${imagePath}`;
  
  return `${cdnUrl}${path}`;
}
```

#### 2. Updated Components
- `/app/design-houses/[slug]/page.tsx`
- `/app/design-houses/[slug]/DesignHouseClient.tsx`
- `/app/components/design-houses/dh-img-swipter.tsx`
- `/app/components/co-creation/cc-design-house-list.tsx`

### Before and After

#### Before (Problematic)
```tsx
<Image src={`${AWS_CDN_URL}${dh.logo}`} />
```

#### After (Fixed)
```tsx
import { getImageUrl } from "@/utils/imageHelper";

<Image src={getImageUrl(dh.logo)} />
```

## Benefits
1. **Robust URL Construction**: Handles various input formats safely
2. **Centralized Logic**: Single source of truth for image URL generation
3. **Maintainable**: Easy to update logic across the entire application
4. **Type Safe**: TypeScript support with proper type checking
5. **Future-Proof**: Additional helper functions available for complex scenarios

## Additional Utilities
The imageHelper.ts also provides:
- `getImageUrlWithFallback()`: For fallback image handling
- `isCDNUrl()`: To validate if a URL is from the configured CDN

## Testing
- ✅ No TypeScript errors
- ✅ Proper URL construction
- ✅ Compatible with Next.js Image optimization
- ✅ Works with existing image paths

## Next Steps
Consider updating other components throughout the application that use AWS_CDN_URL to use this centralized utility for consistency and to prevent similar issues.
