one with the plug in inactive (the corner of the image are curved, this is what i want): https://dev2.alexiscollaudin-digital.fr/wp-content/uploads/2021/04/Capture-de?cran-2021-04-12-a?-22.44.49.png
and the second is whit the plug in activated : https://dev2.alexiscollaudin-digital.fr/wp-content/uploads/2021/04/Capture-de?cran-2021-04-12-a?-22.43.24.png

How can i have the corner like it is on the first picture (it is set like this in my Divi Theme ?

Hi
Now I understand, add this CSS to your style (in you theme) and you will see the image with border radius

.tp-image-wrapper .tp-image,
.tp-image-wrapper .tp-image-hover{
    border-radius: 15px;
}
