    I do not know what you will actually do but this is the approach that best fits

    when you put a file type in your form, you need to use the global variable Files

    form.html

     <form action="process.php" method="post" enctype="multipart/form-data">
      <label for="picture">Picture:</label>
      <input type="file" name="picture" id="picture"><br>
      <input type="submit" name="submit" value="Upload">
    </form>
    

    process.php

    <?php
        session_start();
        //make sure you have created the **upload** directory
        $filename    = $_FILES["picture"]["tmp_name"];
        $destination = "upload/" . $_FILES["picture"]["name"]; 
        move_uploaded_file($filename, $destination); //save uploaded picture in your directory
    
        $_SESSION['user_name6'] = $destination;
    
        header('Location: display_picture.php');
    

    display_picture.php

    <?php
    session_start();
    ?>
    <div>
      <img src="<?php echo $_SESSION['user_name6']; ?>" alt="picture"/>
    </div>
