example on using modified orbit foundation and lazyload. notice that each time the slide change, it triggers the lazyload to load the image.

site.js

$('.products-slider').orbit({
  fluid: "1100x350",
  timer: false,
  afterSlideChange: function(){
    this.$slides
      .eq(this.activeSlide)
      .find('img.lazyload').trigger('appear');
  }
});
