As this was specific wordpress question and I found an answed, i will share it. When you add custom image size to functions.php, add 9999 to width and hardCrop to false.
由于这是特定的 wordpress 问题，我找到了一个答案，我将分享它。在向functions.php 添加自定义图像大小时，将9999 添加到width 并将hardCrop 添加到false。
add_image_size('slider-thumb-alt', 9999, YOUR_FIXED_HEIGT, false);

First when importing them via the media manager you can define the native size. Otherwise you will have to hard code them like @Dan Grossman mentioned. We need more info. Site link and slider name?
首先，当通过媒体管理器导入它们时，您可以定义本机大小。否则你将不得不像@Dan Grossman 提到的那样对它们进行硬编码。我们需要更多信息。站点链接和滑块名称？

It sounds like you already have a pretty decent idea of what you need. Use css to do this.
听起来您已经很清楚自己需要什么。使用 css 来做到这一点。
For example:
例如：
<img src="http://www.example.com/image.jpg" class="image_class"/>
<style>
.image_class{
width: auto;
height:330px;
</style>
You'll want to target based on class (rather than all images with img{...}). I haven't used WP Slider, but I'm assuming that it will add a custom class to images in the slider. If so just use your in-browser developer tools, or view source, to see what class is being added to these images, then create the css like the above.
您将希望基于类（而不是所有带有 的图像img{...}）进行定位。我没有使用过 WP Slider，但我假设它会为滑块中的图像添加一个自定义类。如果是这样，只需使用您的浏览器内开发工具或查看源代码，查看添加到这些图像的类，然后像上面一样创建 css。
