🛡️ Error-Safe Usage (Recommended)

The package offers bulletproof error handling that ensures your application never breaks due to missing images or storage issues.

Silent Mode (Never Fails)

{{-- ✅ NEVER throws exceptions, always shows something --}}
<img src="{{ Thumbnail::set('gallery')->src($photo->path, 's3')->urlSafe() }}" alt="Gallery">

{{-- ✅ Explicit silent mode --}}
<img src="{{ Thumbnail::silent()->set('products')->src($image, 's3')->url('thumb') }}" alt="Product">

Strict Mode (For Development/Admin)

{{-- ⚠️ May throw exceptions for debugging --}}
<img src="{{ Thumbnail::strict()->set('gallery')->src($photo->path, 's3')->url() }}" alt="Gallery">

{{-- ⚠️ Standard mode (configurable default) --}}
<img src="{{ Thumbnail::set('gallery')->src($photo->path, 's3')->url('large') }}" alt="Gallery">

🎯 Quick Examples

Responsive Blog Headers

<picture>
    <source media="(max-width: 640px)" 
            srcset="{{ Thumbnail::set('blog')->src($post->image, 's3')->urlSafe('card') }}">
    <source media="(min-width: 641px)" 
            srcset="{{ Thumbnail::set('blog')->src($post->image, 's3')->urlSafe('hero') }}">
    <img src="{{ Thumbnail::set('blog')->src($post->image, 's3')->urlSafe('hero') }}" 
         alt="{{ $post->title }}"
         loading="lazy">
</picture>

Homepage Slider (Never Breaks)

<div class="hero-slider">
    @foreach($slides as $slide)
        <div class="slide">
            {{-- This slider will NEVER break, even with missing images --}}
            <img src="{{ Thumbnail::set('slider')->src($slide->image, 's3')->urlSafe('desktop') }}"
                 alt="Hero Slide"
                 loading="lazy">
        </div>
    @endforeach
</div>

⚙️ Advanced Configuration

Multi-Disk Setup

// config/filesystems.php
'disks' => [
    's3_products' => [
        'driver' => 'scoped',
        'disk' => 's3',
        'prefix' => 'products',
    ],
    's3_gallery' => [
        'driver' => 'scoped',
        'disk' => 's3',
        'prefix' => 'gallery',
    ],
],

Preset Configuration

// config/thumbnails.php
'presets' => [
    'products' => [
        'format' => 'webp',
        'smartcrop' => '400x400',
        'destination' => ['disk' => 's3_products', 'path' => 'thumbnails/'],
        'quality' => 90,
        'smart_crop_enabled' => true,
        'silent_mode' => false, // Strict for admin
        'subdirectory_strategy' => 'hash_prefix', // Optimal for high volume
        'variants' => [
            'thumb' => ['smartcrop' => '120x120', 'quality' => 75],
            'card' => ['smartcrop' => '250x250', 'quality' => 85],
            'detail' => ['smartcrop' => '600x600', 'quality' => 95],
            'zoom' => ['smartcrop' => '1200x1200', 'quality' => 95],
        ]
    ],
],

📁 Subdirectory Organization

Handle millions of thumbnails efficiently with automatic subdirectory organization:

Hash Prefix Strategy (Recommended)

thumbnails/products/
├── a/b/ (47 files)
├── c/d/ (52 files)
├── e/f/ (48 files)
└── ... (256 total directories)

Date-Based Strategy

thumbnails/blog/
├── 2025/01/28/ (today's posts)
├── 2025/01/27/ (yesterday's posts)
└── 2025/01/26/ (older posts)

Configuration

'subdirectory_strategy' => 'hash_prefix',    // Uniform distribution (recommended)
'subdirectory_strategy' => 'date_based',     // Organized by date
'subdirectory_strategy' => 'filename_prefix', // By filename initials
'subdirectory_strategy' => 'hash_levels',    // Multi-level (a/b/c/)
'subdirectory_strategy' => 'none',           // No subdirectories

🧠 Smart Crop Algorithm

Advanced intelligent cropping based on image energy analysis:

// Enable smart crop for better results
'smart_crop_enabled' => true,  // Uses energy detection algorithm
'smart_crop_enabled' => false, // Uses simple center crop

How it works:

• Analyzes image energy using gradient magnitude
• Finds areas of interest based on contrast and details
• Avoids aggressive cropping that removes important subjects
• Uses rule of thirds for optimal positioning

🛠️ Artisan Commands

Purge Thumbnails

# Purge all thumbnails
php artisan thumbnail:purge

# Purge specific preset
php artisan thumbnail:purge products

# Silent purge (no confirmation)
php artisan thumbnail:purge products --confirm

Statistics & Analysis

php artisan tinker
>>> Thumbnail::analyzeDistribution('products')
>>> Thumbnail::getSystemStats()
>>> Thumbnail::optimize() // Remove duplicates and empty directories

🎛️ Advanced Features

Conditional Error Handling

{{-- Admin sees errors, users get safe fallbacks --}}
@admin
    <img src="{{ Thumbnail::strict()->set('gallery')->src($image, 's3')->url() }}" alt="Gallery">
@else
    <img src="{{ Thumbnail::silent()->set('gallery')->src($image, 's3')->url() }}" alt="Gallery">
@endadmin

Performance Optimization

        'subdirectory_strategy' => 'hash_prefix',
        'quality' => 75,
        'silent_mode' => true,
    ],
    'high_quality' => [
        'quality' => 95,
        'webp_lossless' => true,
        'silent_mode' => false,
    ],
],

Batch Processing

// Process multiple thumbnails efficiently
'batch_size' => 50,
'batch_timeout' => 300,

'max_file_size' => 10 * 1024 * 1024, // 10MB
'validate_image_content' => true,
'sanitize_filenames' => true,

📊 Monitoring & Statistics

System Analysis

// Get complete system statistics
$stats = Thumbnail::getSystemStats();
// Returns: total files, size, distribution by disk, preset analysis

// Analyze specific preset
$analysis = Thumbnail::analyzeDistribution('products');
// Returns: file count, size, directory distribution, format breakdown

Performance Monitoring

'enable_stats' => true,
'log_generation_time' => true,
'monitor_disk_usage' => true,

🔧 Troubleshooting

Common Issues

# Test disk connectivity
php artisan tinker
>>> Thumbnail::testDisk('s3_products')

# Validate configuration
>>> Thumbnail::validateConfiguration()

# Clear Laravel caches
php artisan config:clear
php artisan cache:clear

Debug Mode

{{-- Debug information in development --}}
@if(app()->environment('local'))
    @foreach(Thumbnail::getAvailableDisks() as $disk)
        @php $status = Thumbnail::testDisk($disk) @endphp
        <p>{{ $disk }}: {{ $status['accessible'] ? '✅' : '❌' }}</p>
    @endforeach
@endif
