Photo Management System

Overview

The Photo Management System allows users to upload, organize, and display photos for parks in the ThrillWiki application. This document outlines the implementation details, architecture, and key components of the system.

Components

Models

• Photo Model: Polymorphic model that can be associated with any entity (currently used with Parks)
  • Attributes: title, description, file_path, file_name, file_size, mime_type, width, height, position, is_featured, alt_text, credit, source_url, metadata
  • Relationships: morphTo photoable (currently Park)
  • Methods: setAsFeatured, updatePosition, getUrlAttribute, getThumbnailUrlAttribute

Controllers

• PhotoController: Handles CRUD operations for photos
  • Methods: index, store, show, update, destroy
  • Responsibilities: File upload handling, validation, thumbnail generation

Livewire Components

• PhotoUploadComponent: Handles photo upload UI and processing
• PhotoGalleryComponent: Displays photos in a gallery format
• PhotoManagerComponent: Allows reordering and deleting photos
• FeaturedPhotoSelectorComponent: UI for selecting featured photos

API Endpoints

• RESTful endpoints for photo management
• Endpoints for reordering photos
• Endpoint for setting featured photos

Storage Configuration

• Public disk for storing photos
• Directory structure: storage/app/public/photos/{entity_type}/{entity_id}/
• Thumbnail generation and optimization
• File naming convention: {timestamp}_{original_filename}

Technical Decisions

File Storage

• Using Laravel's public disk for storing photos
• Files accessible via /storage/photos/...
• Thumbnails generated at upload time
• Original files preserved

Image Processing

• Using Intervention Image for thumbnail generation
• Thumbnails created at 300x300px (maintaining aspect ratio)
• Original images preserved
• JPEG compression for web optimization

Security Considerations

• Strict file type validation
• File size limits (10MB max)
• Proper authorization checks
• Sanitized filenames

Usage Examples

Adding a Photo to a Park

$park->addPhoto([
    'title' => 'Park Entrance',
    'description' => 'Main entrance to the park',
    'file_path' => 'photos/parks/123/entrance.jpg',
    'file_name' => 'entrance.jpg',
    'is_featured' => true
]);

Setting a Featured Photo

$park->setFeaturedPhoto($photoId);

Reordering Photos

$park->reorderPhotos([3, 1, 4, 2]); // Array of photo IDs in desired order

Future Enhancements

• Support for additional entity types (rides, attractions)
• Advanced image editing capabilities
• Bulk upload functionality
• Image tagging and categorization
• EXIF data extraction and display
