Transforms images on demand via Netlify Image CDN's /.netlify/images endpoint with query parameters for resizing/cropping/format/quality. Use when adding image optimization or responsive images, converting formats (WebP/AVIF/PNG), generating thumbnails or blur placeholders, serving remote/third-party images through the CDN, allowlisting remote domains in netlify.toml, setting up image redirects or cache headers, building user-uploaded image pipelines, or debugging a 404 on /.netlify/images. Also covers framework image handling for Angular/Astro/Gatsby/Next.js/Nuxt.
