Sitemaps has truly been a basic SEO step for many large or
even medium sized web sites. Google Image search has been a strong driver of
traffic to many sites, but sometimes it is hard for webmasters to get their
images indexed. Google announced support for images in Sitemaps.
Here
is an example:
style="display:inline-block;width:468px;height:60px"
data-ad-client="ca-pub-1808363501347209"
data-ad-slot="7098150979">
With this you can specify image, location, caption,
geolocation, title and license.
