Rendering the Image component with an absolute URL whose hostname is not configured throws at render time, with a message that the src prop is invalid because the hostname is not configured under images in next.config.

Since Next.js 15 remotePatterns is the supported field and the older images.domains array is deprecated. A remotePatterns entry takes protocol, hostname, port and pathname, and the hostname supports a single leading wildcard segment. Be specific with it: a broad wildcard turns your deployment into an open image resizing proxy that anyone can drive.

For images you do not control, or when optimization is not wanted, set the unoptimized prop or configure a custom loader. In a static export the built in optimizer is unavailable, so one of those two is mandatory.
