How to add drop shadow to LIST IMAGE

Site URL: http://www.dalmanpressurewashing.com

last week I had figured out a way to add a boxshadow/dropshadow to images in a list but accidently deleted the code and I completely forgot what I did

If you use .list-item  {
  filter: drop-shadow(5px 5px 5px #000000);
}

You can add a drop shadow to a list image but it also adds one to the text and button I only want the shadow on the image.

There isn't one resource on the internet I can find. I totally forgot how I did it before please help I am pulling my hair out because it's so simple but I just can't remember.

This is a question about LIST IMAGES NOT REGULAR IMAGES

Can you try this code?:

.list-item .list-item-media{
  filter: drop-shadow(5px 5px 5px #000000);
}

The list-item-media class ensures that the property applies only to the images.
