When I try to show an uploaded image html shows me another one but if I refresh the page it shows me the right one

I made a page for an e-commerce website where if you want to add images you select them and you upload everything to the server. The problem is (like I mentioned on the title) that he shows me images uploaded before and when I refresh the page it displays the right one. I alredy tried to make a location.reload() with javascript but I don't like the fact that he has to load the page twice. Also I noticed that on mobile phones and on tablet (connected at the same wi-fi of my pc) it takes a lot of time to upload images.

Here's the code:

<html>
 <head>
 </head>
 <body>
 <div class="container">
  <div id="ctn1">
    <form enctype="multipart/form-data" method="post" action="aggiungi_immagini.php">
      <div class="fileUpload btn btn-primary">
        <span>Seleziona Immagini</span>
        <input id="uploadBtn" class="upload" type="file" name="files[]" multiple>
      </div>
      <input id="uploadFile" placeholder="Nessun File selezionato" disabled="disabled" /><br>
      <input type="submit" value="Carica" class="btn btn-primary">
    </form><br>
    <?php
    $files = array();
    foreach (new DirectoryIterator('images/'.$_SESSION['prodid'].'/') as $fileInfo) {
        if($fileInfo->isDot() || !$fileInfo->isFile()) continue;
        $files[] = $fileInfo->getFilename();
    }
    foreach ($files as $filename) {

    ?>
      <style>
        #imagelisticon{
          color: rgba(255, 255, 255, 0.5);
          position: absolute;
          margin-left:-100px;
          z-index: 2;
          background-color: rgba(0, 0, 0, 0.2);
          line-height: 200px;
          height: 200px;
          width:200px;
          font-size: 40px;
        }
        #imgcnt{
          background-size: cover;
          background-repeat: no-repeat;
          position:relative;
          margin-top:40px;
          width:200px;
          height:200px;
          display: inline-block;
          border: 1px solid lightgrey;
          line-height: 198px;
          overflow: hidden;
        }
        .trash{
          position: absolute;
          vertical-align: text-top;
          margin-top: 5px;
          margin-left: 50px;
          z-index:3;
        }
      </style>
        <div id="imgcnt" style="background-image: url('images/<?php echo $id;?>/<?php echo $filename;?>');">

            }
        }

    }?>

        <?php
    }


?>


</body>
</html>
<script>
document.getElementById("uploadBtn").onchange = function () {
  document.getElementById("uploadFile").value = this.value;
};
$("DIV[class='btn btn-danger trash']").click(function(){
    var delfile = ($(this).attr("id"))
      $.ajax({
        type: 'post',
        url: 'delete.php',
        data: {
            source1: delfile
        },
        success: function( data ) {
            console.log( data );
        }
    });
})

</script> 

Sorry if the code is long and not well-indentated but I screwed up to fit it in the code format :)

By the way I know the code is a little long so I'll show you the part where I echo the pics:

<?php
$files = array();
foreach (new DirectoryIterator('images/'.$_SESSION['prodid'].'/') as $fileInfo) {
    if($fileInfo->isDot() || !$fileInfo->isFile()) continue;
    $files[] = $fileInfo->getFilename();
}
foreach ($files as $filename) {

?>
    <div id="imgcnt" style="background-image: url('images/<?php echo $id;?>/<?php echo $filename;?>');">
      <div id="<?php echo $filename;?>" class="btn btn-danger trash"><i class="fa fa-trash" aria-hidden="true"></i></div>
      <i id="imagelisticon" class="fa fa-check" aria-hidden="true"></i>
    </div>
<?php
    }
?>

P.S. I removed the style part so you can see the back-end.

I store my images in the directory 'images' and then in a directory that has the name of the id of the product I want to link images. So if I want to store images for the product that has id=25, images will be in this path: "images/25/"

Thanks for helping me, I relly need to find a method to solve this problem.
