-
-Checks the storage directory structure and verifies that photo files exist.
-
-### Usage:
-```bash
-# Check overall storage structure
-node scripts/check-storage.js
-
-# Check specific event
-node scripts/check-storage.js wedding-test-gallery-2025-07-14-1
-```
-
-### What it checks:
-- Storage directory structure and permissions
-- Event directories
-- Photo files existence
-- Thumbnail files existence
-- Database vs filesystem consistency
-
-## regenerate-thumbnails.js
-
-Regenerates missing thumbnails for photos in the database.
-
-### Usage:
-```bash
-# Regenerate all missing thumbnails
-node scripts/regenerate-thumbnails.js
-
-# Regenerate thumbnails for specific event (by ID)
-node scripts/regenerate-thumbnails.js 2
-```
-
-### What it does:
-- Scans photos in database
-- Checks if thumbnails exist
-- Generates missing thumbnails using Sharp
-- Updates database with thumbnail paths
-- Reports success/error statistics
-
-### Prerequisites:
-- Node.js environment
-- Database access
-- Write permissions to storage directory
-- Sharp library installed
-
-## Production Usage
-
-On your production server:
-
-1. First, check the storage structure:
-   ```bash
-   cd /path/to/picpeak/backend
-   NODE_ENV=production node scripts/check-storage.js wedding-test-gallery-2025-07-14-1
-   ```
-
-2. If thumbnails are missing, regenerate them:
-   ```bash
-   NODE_ENV=production node scripts/regenerate-thumbnails.js 2
-   ```
-
-Note: Replace `2` with the actual event ID from your database.
-
-## cleanup-thumbnails.js
-
-Cleans up temporary and orphaned thumbnail files.
-
-### Usage:
-```bash
-# Dry run - see what would be deleted
-node scripts/cleanup-thumbnails.js --dry-run
-
-# Actually delete orphaned thumbnails
-node scripts/cleanup-thumbnails.js
-```
-
-### What it does:
-- Identifies temporary thumbnails (thumb_temp_*)
-- Finds orphaned thumbnails not linked to any photo
-- Removes unnecessary files to free up space
-- Reports statistics on cleanup
-
-## diagnose-thumbnails.js
-
-Diagnoses why thumbnails might not be showing for a specific event.
-
-### Usage:
-```bash
-node scripts/diagnose-thumbnails.js 2
-```
-
-### What it checks:
-- Thumbnail paths in database vs filesystem
-- Path format inconsistencies
-- Missing thumbnail files
-- Provides SQL to fix path issues
-
-### Common Issues:
-1. **Path mismatch**: Database has wrong thumbnail path format
-2. **Missing files**: Thumbnails were never generated
-3. **Permission issues**: Web server can't read thumbnail files
