[Plugin: WordPress SEO by Yoast] Nextgen gallery indexed in Sitemap?

Hi everyone,

I was just wondering if the latest version of WordPress SEO is indexing the pictures in my Nextgen galleries. I’ve activated the function of creating the XML sitemaps, but how do I know that WordPress SEO is indexing those images?

Thanks!

Edoardo
