在下面的片段中，我无法复制我网站上的问题。但是，我可以说我已经将问题缩小到Slick Slider。这个问题在我开始使用之前没有发生，当我删除这个特定的滑块时，这个问题就消失了。
问题是，我正在处理的页面上的许多图像正在增长到一些荒谬的高度。例如，在滑块中，有一张柯南奥布莱恩的照片。在我的网站上，图像的宽度超过123，000像素。
同样，我不能重复的问题，但如果你知道一个具体的问题，并与光滑滑块修复，我会很感激。

$('.slider').slick({
        infinite: true,
        speed: 800,
        slidesToShow: 1
      });

      $('.left').click(function () {
        $('.slider').slick('slickPrev');
      });

      $('.right').click(function () {
        $('.slider').slick('slickNext');
      });
