How can I achieve this in pure css? I’m trying to achieve by using pseudo before and after. Maybe some tweaking on the border but I can’t think of a way to recreate this.

This is what I have so far: CSS

.imageDiv {
  background-image:url('https://picsum.photos/id/64/4326/2884')
  width: 160px;
  height: 135px;
  border-radius: 5px;
  opacity: 1;
  display: flex;
  justify-content: center;
  flex-direction: column;
  align-items: center;
  background-position: center;
  background-size: cover;
  margin-left: auto;
  position: relative;
}

.imageDiv::after {
  position: absolute;
  width: 100%;
  height: 100%;
  border-radius: 100%;
  background-color: #ffffff61;
  content: "";
}

<div class="imageDiv" style="background-image:url('https://picsum.photos/id/64/4326/2884')">
  <label class="imageText">
      Cambiar photo
  </label>
</div>

One approach is below, making use of the mask-image() CSS property along with a radial-gradient() to create the circular shape; the code contains explanatory comments:

:root {
  --main-inline-size: 80%;
  --main-max-inline-size: 1200px;
  --main-min-inline-size: 20rem;
  --spacing: 0.5rem;
}

*,
::before,
::after {
  box-sizing: border-box;
  font: inherit;
  margin: 0;
  padding: 0;
}

body {
  block-size: 100vh;
  font-family: system-ui;
  font-size: 16px;
  font-weight: 400;
  padding: var(--spacing);
}

menu,
ol,
ul,
li {
  list-style-type: none;
}

main {
  border: 1px solid currentColor;
  inline-size: clamp(var(--main-min-inline-size), var(--main-inline-size), var(--main-max-inline-size));
  margin-inline: auto;
  min-block-size: 100%;
  padding: var(--spacing);
}

/* Everything above/prior to this point is irrelevant to the demo
   and is purely to serve as a simple reset, and base-style */

figure {
  /* in order to use grid-layout, while also retaining an inline
     aspect to allow adjacent content: */
  display: inline-grid;
  grid-template-rows: fit-content;
  overflow: hidden;
  position: relative;
}

figure > * {
  /* placing all the children of <figure> in the first column
     of the first row: */
  grid-column: 1;
  grid-row: 1;
}

img {
  /* this is for Chrome, and presumably other Chromium-based
     browsers as, despite the comments on both MDN and
     CanIUse (see the links in the "compatibility" section, below)
     it seems that Chrome doesn't (yet) support the non-prefixed
     version of mask-image, unfortunately necessitating the use
     of the prefixed version: */
  -webkit-mask-image: radial-gradient(black 60%, #fffa 60%);
  /* creating the mask, using CSS radial-gradient(),
     from black (the 'transparent'/'clear' central circle)
     to a lightly transparent white color; both color
     stops are at 60% for a transition at that point: */
  mask-image: radial-gradient(black 60%, #fffa 60%);
}

/* largely irrelevant, just for presentation */

figcaption {
  align-self: end;
  backdrop-filter: blur(3px);
  background-color: #fff9;
  padding-block: 0.25rem;
  padding-inline: 0.5rem;
  transition: translate 0.3s linear;
  translate: 0 100%;
}

figure:hover figcaption {
  translate: 0 0;
}

<main>
  <figure>
      <img src="//picsum.photos/400/400" alt="">
    <figcaption>Cambiar photo</figcaption>
  </figure>
</main>

JS Fiddle demo.

I completely failed to notice the centred text in the example, so my updated demo addresses that failure (though I retain a transition, on clip-path this time) obviously remove if you don’t want one:

:root {
  --main-inline-size: 80%;
  --main-max-inline-size: 1200px;
  --main-min-inline-size: 20rem;
  --spacing: 0.5rem;
}

*,
::before,
::after {
  box-sizing: border-box;
  font: inherit;
  margin: 0;
  padding: 0;
}

body {
  block-size: 100vh;
  font-family: system-ui;
  font-size: 16px;
  font-weight: 400;
  padding: var(--spacing);
}

menu,
ol,
ul,
li {
  list-style-type: none;
}

main {
  border: 1px solid currentColor;
  inline-size: clamp(var(--main-min-inline-size), var(--main-inline-size), var(--main-max-inline-size));
  margin-inline: auto;
  min-block-size: 100%;
  padding: var(--spacing);
}

figure {
  display: inline-grid;
  grid-template-rows: fit-content;
  overflow: hidden;
  position: relative;
}

figure>* {
  grid-column: 1;
  grid-row: 1;
}

img {
  -webkit-mask-image: radial-gradient(black 60%, #fffa 50%);
  mask-image: radial-gradient(black 60%, #fffa 50%);
}

figcaption {
  backdrop-filter: blur(3px);
  background-color: #fff9;
  clip-path: polygon(50% 0, 50% 0, 50% 100%, 50% 100%);
  font-size: 2rem;
  padding-block: 0.25rem;
  padding-inline: 0.5rem;
  overflow: hidden;
  align-self: center;
  text-align: center;
  transition: clip-path 0.3s linear;
}

figure:hover figcaption {
  clip-path: polygon(0 0, 100% 0, 100% 100%, 0 100%);
}

<main>
  <figure>
    <img src="//picsum.photos/400/400" alt="">
    <figcaption>Cambiar photo</figcaption>
  </figure>
</main>

JS Fiddle demo.

Following the comment left by OP, Benjoe, below, and verifying that statement with Chrome 116, on both Ubuntu 23.04 and Android 13:

I cannot see the circle on your demo and I’m using [Google Chrome].

I’ve edited the above code snippets (and updated the linked JS Fiddle demos, [1, 2]) to include the prefixed -webkit-mask-image property. This has been checked in my installations of Chrome 116 on both platforms available. Feedback would be welcomed if there are other problems.
