next/image does not load images from external URL after deployment

You need to set the configuration in the next.config.js file first.

For Example:

on next.config.js

module.exports = {
    images: {
        domains: ['images.unsplash.com'],
    },
}

on pages/your_page_file.tsx

    width={2250}
    height={1390}
    layout="responsive"
