There are pages (conditionally - height 1800px). At the very bottom of the page is a slider with images. At the moment its html-code is:
<div id="slider" class="slider_wrap"> <div id="slides"> <img src="/img/slider/1.jpg" /> <img src="/img/slider/2.jpg" /> </div> <span class="next"></span><span class="prev"></span> </div>
When you open the page, the first two images are loaded, the rest are loaded as you view the slider.
Attention, the question: how to make the slider begin its work only after the page is scrolled down and the field where the slider itself will appear on the screen? I mean, the first 2 pictures should be loaded only after they got to the slider itself.
