Edge Images vs 站长帮 – WordPress CDN 缓存管理插件

Edge Images automatically uses your edge transformation service (e.g., Cloudflare, Accelerated Domains, Imgix, etc.) to apply performance optimizations to markup. ⚠️ Important: This plugin requires a supported edge provider with image transformation features enabled (e.g., Cloudflare Pro, BunnyCDN, etc). See the Requirements section for details. 🚀 Why should I use Edge Images? Instant Performance Boost: Automatically optimize and serve images in modern formats (WebP/AVIF) through your existing CDN Zero Configuration: Works out of the box with your existing images and themes No Local Processing: All transformations happen at the edge – no server load or storage overhead Perfectly Sized Images: Automatically generates the exact image dimensions needed for every device and viewport Cost Effective: No need for expensive image optimization services or additional storage 🎯 Perfect For Sites with lots of images that need optimization Performance-focused developers and site owners Anyone using Cloudflare, BunnyCDN, or similar services Sites that want modern image formats without the complexity Developers tired of managing multiple image sizes 💡 How It Works WordPress typically creates multiple copies of each uploaded image in different sizes. This approach is inefficient and often results in: Images that are too large or small for their display size Unnecessary storage usage Missing sizes for modern responsive designs Lack of modern format support (WebP/AVIF) Edge Images solves these problems by: Intercepting image requests Determining the optimal size and format needed Using your CDN to transform the image on-demand Caching the result for future requests ⚡️ Features Core Features Automatic WebP/AVIF conversion Intelligent responsive image handling Smart srcset generation Automatic image optimization Optional element wrapping Zero local processing Maintains original images Advanced Features Fine-grained transformation control Multiple CDN provider support Developer-friendly filters Yoast SEO & Rank Math integrations Bricks integration Gutenberg compatibility 🔌 Supported Providers Cloudflare (Pro plan or higher) Accelerated Domains BunnyCDN Imgix 🛠️ Technical Example Your Code echo wp_get_attachment_image(1, [640,400], false, ['fit' => 'contain']); What WordPress Usually Outputs That’s multiple different images files, none of which are the right size! What Edge Images Outputs That’s a range of perfectly sized options for different devices and viewports, automatically optimized images in modern formats, served from your CDN, futureproofed for supporting next-generation capabilities, and with no storage overheads. 🎨 Customization Transform Parameters Control every aspect of image transformation with attributes like: * width/height: Exact dimensions * fit: Resizing behavior (contain, cover, crop) * quality: Compression level * format: Output format (auto, webp, avif) Filtering Disable transformations globally or selectively: // Disable all transformations add_filter('edge_images_disable', '__return_true'); // Disable for specific images add_filter('edge_images_disable_transform', function($should_disable, $html) { if (strpos($html, 'example.jpg') !== false) { return true; } return $should_disable; }, 10, 2); // Override max width for constrained content add_filter('edge_images_max_width', function($max_width) { // Example: Use a different max width for single posts if (is_single()) { return 800; } return $max_width; }); // Customize srcset width multipliers add_filter('edge_images_width_multipliers', function($multipliers) { // Add more granular steps between sizes return [0.25, 0.5, 0.75, 1, 1.25, 1.5, 2]; }); 🔧 Requirements Essential A supported edge provider with image transformation features enabled: Cloudflare Pro plan or higher with Image Resizing enabled Accelerated Domains with Image Resizing enabled BunnyCDN with Image Processing enabled Imgix with a configured source Technical PHP 7.4 or higher WordPress 5.9 or higher ✅ Getting Started Install and activate the plugin Go to Settings > Edge Images Select your CDN provider That’s it!
