html - Overlapping/overlaying multiple inline images

Question

I have a list of images I'm trying to overlap so that they look similar to this:

My code:

.avatar img {
    border-radius: 50%;
    position: relative;
    left: -5px;
    z-index: 1;
}

<div class="avatars">
    <span class="avatar">
        <img src="https://picsum.photos/70" width="25" height="25"/>
    </span>
    <span class="avatar">
        <img src="https://picsum.photos/50" width="25" height="25"/>
    </span>
    <span class="avatar">
        <img src="https://picsum.photos/20" width="25" height="25"/>
    </span>
    <span class="avatar">
        <img src="https://picsum.photos/100" width="25" height="25"/>
    </span>
    <!-- Variable amount more avatars -->
</div>
<p>4 People</p>

You can use flex and reverse order then no need z-index:

.avatars {
  display: inline-flex;
  flex-direction: row-reverse;
}

.avatar {
  position: relative;
  border: 4px solid #fff;
  border-radius: 50%;
  overflow: hidden;
  width: 100px;
}

.avatar:not(:last-child) {
  margin-left: -60px;
}

.avatar img {
  width: 100%;
  display: block;
}

<div class="avatars">
  <span class="avatar">
        <img  src="https://picsum.photos/70">
    </span>
  <span class="avatar">
        <img src="https://picsum.photos/80">
    </span>
  <span class="avatar">
        <img src="https://picsum.photos/90">
    </span>
  <span class="avatar">
       <img src="https://picsum.photos/100">
    </span>
</div>
