XML Sitemap for Media
You can use the Custom sitemap for achieving this


  The Custom Sitemap module allows users/site admins to add custom
  sitemaps to a site, unlike currently available module that binds users
  to build a sitemap using the primary menu.
  
  This module enables you to add or promote random URLs from SEO
  viewpoint. It also facilitates you to add independent sitemaps for all
  domains in a multi domain Drupal setup. This also helps you to have a
  domain specific custom sitemap.
