Индикатори за миниатюри на въртележката на Bootstrap

Копирам този код от примерния код на bootply за въртележка http://www.bootply.com/79859

Но имам проблем с миниатюрата на изображението, защото не работи. Той не се движи върху конкретното изображение, докато голямото изображение се плъзга. Не знам дали съм пропуснал jquery, който ще поддържа индикаторите.
