How to Use the App

🚀 Getting Started

1. Start the Application:

   npm start

   The app will open at http://localhost:3000

2. Initial Load: The app automatically loads recent Flickr photos when you first visit

🔍 Searching for Photos

1. Automatic Search:

   • Type any keyword in the search box (placeholder: "Search in tags")
   • Searches only in photo tags, not titles or descriptions
   • Search requires at least 4 characters to trigger
   • Results appear automatically after 2 seconds of no typing (debouncing)
   • No search button needed - typing triggers search automatically
   • Allows uninterrupted typing of longer words - search only triggers when you stop typing

2. Search Tips:

   • Tag-based search: Only finds photos that are explicitly tagged with your keyword
   • Use specific tag terms for better results (e.g., "landscape", "portrait", "street")
   • Try different keywords if you don't find what you're looking for
   • Clear the search by clicking the "X" button to return to recent photos
   • Note: Photos with keywords only in titles (not tagged) won't appear in results

🖼️ Viewing Images

1. Browse the Gallery:

   • Photos are displayed in a responsive grid layout
   • Hover over images to see a "View Full Size" overlay
   • Images load lazily for better performance

2. View Full Resolution:

   • Click on any image thumbnail to open the full-size version in a new tab
   • This opens the high-resolution image directly from Flickr

3. Image Information:

   • Each image shows the title, author, and relevant tags
   • Author names are clickable links to their Flickr profiles

👤 Exploring Authors

1. Author Profiles:
   • Click on any author name to visit their Flickr profile
   • Opens in a new tab to keep your current search results

🏷️ Understanding Tags

1. Tag System:
   • Tags appear below each image
   • Shows up to 10 most relevant tags
   • Tags help you understand the photo's content and context

📱 Mobile Experience

1. Responsive Design:
   • The app automatically adapts to your screen size
   • Touch-friendly interface on mobile devices
   • Optimized grid layout for different screen sizes

⚡ Performance Features

1. Loading States:

   • Skeleton screens appear while images load
   • Loading spinner in search bar during API calls
   • Smooth transitions and animations

2. Error Handling:

   • If an image fails to load, you'll see a friendly error message
   • Network errors are handled gracefully with retry options

🎯 Pro Tips

• Keyboard Navigation: Use Tab to navigate through interactive elements
• Accessibility: The app includes proper ARIA labels for screen readers
• Performance: Images load progressively for faster initial page load
• Offline: The app gracefully handles network issues

API Reference

The application uses Flickr's public feed API:

• Endpoint: https://api.flickr.com/services/feeds/photos_public.gne
• Format: JSONP
• Search: Tag-based filtering only
• Rate Limiting: No API key required for public feeds

Public Endpoint Limitations

⚠️ Important: The Flickr public feed API has several limitations:

1. Recent Photos Only:

   • Only returns the most recently uploaded public photos
   • No access to historical photos or older uploads
   • Content is limited to what's been uploaded recently

2. Tag-Based Search Only:

   • Search only works with photo tags, not titles or descriptions
   • Photos with keywords only in titles won't appear in search results
   • Only finds photos explicitly tagged by photographers

3. No Advanced Filtering:

   • No date range filtering
   • No user-specific filtering
   • No geographic filtering
   • Limited to basic tag matching

4. For Full Search Capabilities:

   • Use Flickr's full Search API (flickr.photos.search) for title/description search
   • Requires API key registration
   • Supports date ranges, user filtering, and text-based search
