Seperate sitemaps for images & videos?

[motionz]

This is not a very important thing that you should upload separate sitemaps or not. If you are using plugins like SEO by Yoast then they will provide you separate sitemaps, that you may upload to your webmasters tool. But if you are using simple sitemap plugins which provide only a .xml file then it will do all the things together, no need of separate sitemaps.
