In addition to the Twitter and Facebook widgets, you can insert all kinds of other social media via the LiveWhale Feeds widget.
Try a YouTube feed or a Vimeo feed for video, a Flickr or Picasa feed for photos. As most social services include an RSS feed as a standard form of public content stream, you can use them to populate your website.
All feed widgets require is an RSS web address from the service— though you may want some additional help in customizing the content from your Admin.
And, like the other social widgets, all content is cached in case the social service becomes unavailable.
