README

The ultimate thumbnail generation package for Laravel. Featuring intelligent smart-cropping, multi-disk support, automatic subdirectory organization, and bulletproof error handling that ensures your application's UI never breaks.

✨ Features

• 🧠 Intelligent Smart Crop Algorithm - Energy-based detection ensures the most important parts of your images are never cropped out.
• 🛡️ Bulletproof Error Handling - Fails gracefully with automatic fallbacks (original image, placeholders, or generated SVGs) to guarantee your layout remains intact.
• 🖼️ Modern Format Support - Seamlessly generates modern image formats, including WebP and AVIF, for maximum compression and performance.
• 📁 Massive Scale Subdirectories - Handles millions of thumbnails efficiently via customizable subdirectory distribution strategies (e.g., hash prefixes, dates).
• 💾 Multi-Disk Architecture - Fully supports local, S3, scoped disks, and any custom Laravel filesystem.
• 🎨 Responsive Variants - Easily define multiple responsive presets (e.g., thumb, card, hero, zoom) within your configuration.
• ⚡ High Performance & Cache - Utilizes Smart Cache Tagging for targeted invalidation without flushing your entire application cache.
• 🎯 Intervention Image 3.x Ready - Full compatibility with the latest image manipulation APIs.

📋 Requirements

• PHP 8.1 or higher
• Laravel 10.0, 11.0, or 12.0
• Intervention Image 3.9+
• GD or ImageMagick PHP Extension (ImageMagick is required for AVIF support)
• Optional: Redis or Memcached (for cache tagging capabilities)

📦 Installation

Install the package via Composer:

composer require askancy/laravel-smart-thumbnails

Publish the configuration file:

php artisan vendor:publish --tag=laravel-smart-thumbnails-config

🚀 Quick Start

Laravel Smart Thumbnails is designed to be effortless. Use the facade directly in your Blade views:

The Bulletproof "Silent" Mode (Recommended)

This mode never throws exceptions. If an image is missing or the disk fails, it silently falls back to a placeholder.

{{-- Implicit silent mode using urlSafe() --}}
<img src="{{ Thumbnail::set('gallery')->src($photo->path, 's3')->urlSafe() }}" alt="Gallery Image">

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

The "Strict" Mode (For Debugging / Admin Panels)

If you want exceptions to be thrown when something goes wrong (e.g., missing original file), use strict mode:

{{-- May throw an exception if the image is missing --}}
<img src="{{ Thumbnail::strict()->set('gallery')->src($photo->path, 's3')->url() }}" alt="Gallery">

Advanced Responsive Pictures

Leverage configured variants to easily render <picture> tags for responsive designs:

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

⚙️ Configuration

Your config/thumbnails.php file is where the magic happens. You can define multiple "presets", each representing a distinct context (like products, avatars, gallery).

'presets' => [
    'products' => [
        'format' => 'webp',                    // Target format (webp, avif, jpg, png)
        'smartcrop' => '400x400',              // Dimensions for the main thumbnail
        'destination' => [
            'disk' => 'public',                // Target storage disk
            'path' => 'thumbnails/products/'   // Target path
        ],
        'quality' => 85,
        'smart_crop_enabled' => true,          // Use the intelligent cropping algorithm
        'subdirectory_strategy' => 'hash_prefix', // Distribute files to prevent folder limits
        
        // Define responsive variants sharing the same preset logic
        'variants' => [
            'thumb'  => ['smartcrop' => '120x120',  'quality' => 75],
            'card'   => ['smartcrop' => '250x250',  'quality' => 85],
            'detail' => ['smartcrop' => '600x600',  'quality' => 95],
            'zoom'   => ['smartcrop' => '1200x1200', 'quality' => 95],
        ]
    ],
],

AVIF Format Support

For ultra-modern web performance, AVIF provides ~50% smaller file sizes than JPEG and ~30% smaller than WebP. To use AVIF, ensure you have the ImageMagick extension installed and update your driver in config/thumbnails.php:

'intervention_driver' => 'imagick', // Must be 'imagick', GD does not support AVIF yet

Then, simply set 'format' => 'avif' in your presets!

📁 Subdirectory Optimization

When you have millions of images, storing them all in a single folder slows down the filesystem drastically. Smart Thumbnails solves this automatically using customizable strategies:

• 'hash_prefix' (Recommended): Uses the first two characters of the MD5 hash (e.g. a/b/image.jpg). Perfectly distributes files.
• 'date_based': Organizes by generation date (e.g. 2025/12/31/image.jpg).
• 'filename_prefix': Groups by the starting letters of the filename.
• 'hash_levels': Deeper, multi-level nesting for massive scale (e.g. a/b/c/image.jpg).

🛠️ Maintenance & CLI Commands

Keep your application fast and clean using the built-in Artisan commands:

# Purge all generated thumbnails across all disks
php artisan thumbnail:purge

# Purge thumbnails only for a specific preset
php artisan thumbnail:purge products --confirm

You can also analyze your usage via Tinker:

php artisan tinker
>>> Thumbnail::getSystemStats();
>>> Thumbnail::analyzeDistribution('products');

🔄 Upgrade Guide (v2.0)

If you are upgrading from an older version, the transition is 100% backwards compatible. No code changes are required in your views or controllers.

Enhancements included automatically:

• Upgrade to Intervention Image 3.x.
• Better memory management and Cache Tagging (Memcached/Redis recommended).
• Advanced Smart Cropping algorithm optimizations.

Make sure to clear your caches after upgrading:

php artisan cache:clear
php artisan config:clear
