What problem does it solve? Serving unoptimized images slows down sites and wastes bandwidth, and building responsive image markup or user-upload pipelines from scratch is error-prone. This Skill provides the exact endpoint syntax, query parameters, and configuration patterns for Netlify's built-in image transformation service. ## Core Features & Use Cases - On-the-fly transformation: Resize, crop, reformat, and compress images through the /.netlify/images endpoint using query parameters like w, h, fit, fm, and q. - Remote image allowlisting: Configure regex-based remote_images rules in netlify.toml and correctly percent-encode external source URLs. - Clean URL rewrites: Map friendly paths like /img/thumb/:key to transformation presets using redirect rules. - User-uploaded image pipelines: Combine Netlify Functions, Blobs storage, and the Image CDN to accept, store, serve, and optimize user uploads. - Use Case: A developer building a photo gallery on Netlify needs thumbnails and hero images from user uploads; this Skill provides the upload Function, Blobs storage code, and redirect presets to ship the full pipeline. ## Quick Start Set up Netlify Image CDN to serve my /uploads photos as 150x150 cropped thumbnails at clean /img/thumb/ URLs.
