尝试将类
pikachoose
的不透明度设置为1

.pikachoose 
{
  opacity:1 !important;
}

使用z索引执行此操作

CSS

JQUERY

function cycleImages(){

      var $active = $('#slideshow .active');
      var $next = ($active.next().length > 0) ? $active.next() : $('#slideshow img:first');
      $next.css('z-index',2);//move the next image up the pile
      $active.fadeOut(1500,function(){//fade out the top image
          $active.css('z-index',1).show().removeClass('active');//reset the z-index and unhide the image
          $next.css('z-index',3).addClass('active');//make the next image the top one
      });
    }
$(function(){
    setInterval('cycleImages()', 10000);
});

谢谢,我有,但现在它不再褪色了。(效果见网站)褪色意味着一幅图像的不透明度从1降低到0,下一幅图像的不透明度从0增加到1…在问题中,yiu提到你不需要褪色…所以我给出了这个解决方案…我不知道你期望的褪色是什么?哦,我确实想保持褪色,但中间没有白色背景。我用Toggle打错了。编辑它..褪色的beaviour就是这样..你可能想要一些其他的动画..不要褪色
