You use this keyword in an arrow function. So it's not binded to anything. Using a regular function the this keyword is now binded to the image element.

$(".img").mousedown(function() {
  setTimeout(()=>{
    $(".popup").fadeIn(150);
    $(".popup").append($(this).clone());
  }, 1000);
}).mouseup(()=>{
   $(".popup").fadeOut(150);
   $(".popup").children().remove();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div class="popup">

</div>

<div class="grid">
 <div class="img">
  <img src="...">
 </div>
 <div class="img">
  <img src="...">
 </div>
 <div class="img">
  <img src="...">
 </div>
</div>
