<script>
const originalUrls = [
    'https://picsum.photos/id/237/800/600',
    'https://picsum.photos/id/238/800/600',
    'https://picsum.photos/id/239/800/600'
];

const newUrls = [];

for (let i = 238; i <= 239; i++) {
  for (let j = 0; j < 5; j++) {
    newUrls.push(`https://picsum.photos/id/${i}/800/600`);
  }
}

const allUrls = originalUrls.concat(newUrls);

console.log(allUrls);
