Set up localized static file serving such as images or documents, which dynamically change based on the current locale.

    // Call the function to set the right image based on the browser's locale
This HTML page includes an image element with an empty `src`. The `localization.js` script is responsible for setting the appropriate image source based on the user's locale.
/* JavaScript (localization.js) */
function setLocalizedImage() {
  var userLocale = navigator.language || navigator.userLanguage; // Get the browser's locale
  var imagePath = getImagePath(userLocale); // Get the appropriate image path
  document.getElementById('localizedImage').src = imagePath; // Set the image source

function getImagePath(locale) {
  var imageMap = {
    'en-US': 'images/image-en.png',
    'fr-FR': 'images/image-fr.png',
    'es-ES': 'images/image-es.png'
    // Add more localized image paths here
  return imageMap[locale] || 'images/image-default.png'; // Fallback to a default image if the locale is not mapped
The `localization.js` file contains two functions. `setLocalizedImage` retrieves the user's locale and sets the image's `src` to the right path using `getImagePath`. `getImagePath` takes the locale as an argument and returns the corresponding image path; if there is no specific image for the locale, it defaults to a generic image.
/* CSS */
#localizedImage {
  width: 100%;
  max-width: 600px; // Set a max-width for the image if necessary
  height: auto; // Maintain aspect ratio
The CSS provides styles for the image. It ensures the image scales with the width of its container up to a maximum width and maintains its aspect ratio.
