Ticker mode

JS:

$('.bxslider').bxSlider({
  minSlides: 4,
  maxSlides: 4,
  slideWidth: 170,
  slideMargin: 10,
  ticker: true,
  speed: 6000
});

HTML:

<ul class="bxslider">
  <li><img src="/images/170_200/trees.jpg" /></li>
  <li><img src="/images/170_200/tree_root.jpg" /></li>
  <li><img src="/images/170_200/houses.jpg" /></li>
  <li><img src="/images/170_200/hill_road.jpg" /></li>
  <li><img src="/images/170_200/me_trees.jpg" /></li>
  <li><img src="/images/170_200/hill_trees.jpg" /></li>
  <li><img src="/images/170_200/mountain.jpg" /></li>
  <li><img src="/images/170_200/houses.jpg" /></li>
</ul>

Note that in order to make the ticker appear slower, the speed value must be raised.
