Слайдер не может быть установлен как плагин, нужно весь код вписывать вручную на разные страницы.

Некто Scott Nix created a child theme for Thematic Framework. It's fully responsive and have other advantages. The menu is responsive and functional (good but not the best). The theme uses FlexSlider.

Цитирую автора темы.

"Added WooThemes Flexslider which works off of sticky posts, it is currently set up to show featured images of 750px wide by 425px height, which can easily be changed. You just have to settle on a specific size and make sure they are saved as the same size when using this option. If you have no sticky posts, the slider just won’t show, and best of all, the slider assets won’t load."
