使用php从mysql显示图像

Question

我想显示数据库中的图像。我的图像字段的数据类型是BLOB。我在本网站的其他一些问题中使用了代码，但代码不起作用。我想在Google地图的信息窗口中显示图片。根据屏幕截图，图像标签正在显示，但图像本身不是。

我的代码：

<?php 
    require "connect.php";

    $sql = "SELECT * FROM tblLocation";
    $result = mysqli_query($conn,$sql);
    $count = mysqli_num_rows($result);

echo "<script>

        function initMap() {

            var infowindow = new google.maps.InfoWindow();

            var uluru = {lat: 14.617766, lng: 121.057154};
            var map = new google.maps.Map(document.getElementById('map'), {
              zoom: 4,
              center: uluru
            });";
            if ($count > 0){
                while ($row = mysqli_fetch_array($result)) {
                    echo "var content = '<div class=".'content'.">'+
                                            '<img src=".'data:image/jpeg;base64,'.base64_encode($row['image'])."'/>'+
                                            '<p>".$row['address']."</p>'+
