In what scenarios or applications would it be beneficial for users to preview images before uploading them to a server using PHP?

When users upload images to a server using PHP, it can be beneficial to provide them with a preview of the image before finalizing the upload. This can help users ensure they are uploading the correct image and make any necessary adjustments before submitting it. By allowing users to preview images before uploading, it can help reduce errors and improve the overall user experience. 

<?php
if(isset($_FILES['image'])){
    $file_name = $_FILES['image']['name'];
    $file_tmp = $_FILES['image']['tmp_name'];
    $file_type = $_FILES['image']['type'];

    // Display image preview
    echo "<img src='data:".$file_type.";base64,".base64_encode(file_get_contents($file_tmp))."' />";
}
?>
