如何使用jQuery显示数据库中的图像

Question

我在使用jquery显示图像时遇到问题。从数据库中检索图像，我想使用jquery显示它。下面是我的代码

index.php

<?php 
require_once("db.php");

if(isset($_POST['input'])):

$id = $_POST['id'];

    $selectImage = mysqli_prepare($link,"SELECT product_image FROM products WHERE id = ? ");
    mysqli_stmt_bind_param($selectImage, "i",$id);
    mysqli_stmt_execute($selectImage);
    mysqli_stmt_bind_result($selectImage,$image);
    mysqli_stmt_fetch($selectImage);

    if($image):
      echo $image;

    else:
       echo "no image to display";
    endif;

endif;
?>

ajax.php

function imgViews(){
    $(".imageView").click(function(){
        var id = $(this).attr("id");

        $.ajax({
                url: 'class/display_image.php',
                type: 'POST',
                data: {input: 'input',
                       id:id
                   },
                success:function(data){
                 ****display image*****
                },
                dataType: "text"
