document.getElementById("cont").innerHTML='<div id="yc-mod-slider"><div class="wrapper"><div id="slideshow" class="box_skitter fn-clear"><ul><li><img class="cubeRandom" src="images/slider1.jpg" /></li><li><img class="cubeRandom" src="images/slider2.jpg" /></li><li><img class="cubeRandom" src="images/slider3.jpg" /></li></ul></div></div></div>';

去掉这三个div后可以显示这三张图片
