For each URL you list in your sitemap, you can add additional information about important images on that page. The following example shows a sitemap entry for the URL
http://example.com/sample.html, which contains two images.
You can list up to 1,000 images for each page, using the syntax outline in the example above!
<?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1"> <url> <loc>http://example.com/sample.html</loc> <image:image> <image:loc>http://example.com/image.jpg</image:loc> </image:image> <image:image> <image:loc>http://example.com/photo.jpg</image:loc> </image:image> </url> </urlset>

If, for example, you use a content delivery network (CDN) to host your images, make sure that the hosting site is verified in Search Console OR that you submit your sitemap using
