Implemented complete session management system for multiple users:
**New Features:**
- Isolated user sessions with unique session IDs
- File-based image storage (not in PHP session)
- Automatic 24-hour image expiration
- Session directories: uploads/sessions/{session_id}/
- Images stored with metadata (creation time, expiry, MIME type)
**New Files:**
- session_manager.php - Complete session management class
- cleanup.php - Cron script to delete expired images
- uploads/.htaccess - Security: prevent direct file access
**Updated Files:**
- api.php - Uses SessionManager for file-based storage
- index.php - Loads images from disk via SessionManager
- .gitignore - Exclude user uploads from repository
**Usage:**
- Each user gets isolated session automatically
- Images auto-delete after 24 hours
- Run cleanup.php via cron: `0 * * * * php cleanup.php`
**Security:**
- Session IDs regenerated on first access
- Upload directory protected by .htaccess
- User images isolated by session
