I’d like to position an element (using ::before/::after) relative to an image (using background-image), but it doesn’t seem to work.

If I add position: absolute to &--right::after will the &--right element be the closest parent with position relative?

I mean the element should be in the lower right corner but it appears in the middle. I think it shouldn’t be there since I position it relative to its parent?

I was trying to do my best to explain, but English is not my first language. I believe the screenshots I added below will explain better

Here is simple example for before and after image set and how to use for your criteria

.main-image-container {
      position: relative;
      width: 250px; /* Adjust the width as needed */
      height: 400px; /* Adjust the height as needed */
    }

    .main-image {
      width: 100%;
      height: 100%;
      object-fit: cover;
    }

    .main-image-container::before {
      content: "";
      position: absolute;
      top: -20px;
      right: -20px;
      width: 50px; /* Adjust the width of the top-right image */
      height: 50px; /* Adjust the height of the top-right image */
      background: url('https://i.pinimg.com/564x/4e/96/cb/4e96cbd357952869a1bc20c34f1b01e3.jpg') center/cover no-repeat; /* Replace with your random image path */
      z-index: 1; 
    }

    .main-image-container::after {
      content: "";
      position: absolute;
      bottom: -20px;
      left: -20px;
      width: 50px; /* Adjust the width of the bottom-left image */
      height: 50px; /* Adjust the height of the bottom-left image */
      background: url('https://i.pinimg.com/564x/4e/96/cb/4e96cbd357952869a1bc20c34f1b01e3.jpg') center/cover no-repeat; /* Replace with your random image path */
      z-index: 1; 
    }

As the image is set as a background-image, there is no real need for the pseudo-elements ::before and ::after.

You can have multiple background-image and set their respective size and position:

  background-image: url("https://placehold.co/100x100/orange/white"), url("https://placehold.co/150x100/blue/white"), url("https://placehold.co/600x400");
  background-size: 100px 100px, 150px 100px, cover;
  background-position: bottom left, top right, center;

* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

.header__hero--right {
  background-image: url("https://placehold.co/100x100/orange/white"), url("https://placehold.co/150x100/blue/white"), url("https://placehold.co/600x400");
  height: 400px;
  width: 500px;
  background-size: 100px 100px, 150px 100px, cover;
  object-fit: cover;
  background-position: bottom left, top right, center;
  background-repeat: no-repeat;
}

<div class="header__hero--right">
</div>
