是否可以将图像路径插入到数组中以及如何使用PHP进行操作？

I need help in inserting image path into arrays. Is it even possible? Firstly, I have created a table for accepting random comments from the user then inside that table I have a path for images that I want to call at the same time as the text. I have no problem displaying the texts such as username, password but when I add the path to it, it only displays the URL literally. How would I display the image?

Here is my PHP code:

<?php

require("admin.config.inc.php");

//initial query
$query = "Select * FROM adComments";

//execute query
try {
    $stmt   = $db->prepare($query);
    $result = $stmt->execute($query_params);
}
catch (PDOException $ex) {
    $response["success"] = 0;
    $response["message"] = "Database Error!";
    die(json_encode($response));
}

// Finally, we can retrieve all of the found rows into an array using fetchAll 
$rows = $stmt->fetchAll();


if ($rows) {
    $response["success"] = 1;
    $response["message"] = "Post Available!";
    $response["posts"]   = array();

    foreach ($rows as $row) {
        $post             = array();
    $post["post_id"]  = $row["post_id"];
    $post['img'] = 'http://www.stagconnect.com/StagConnect/admin/pictures/'.$row["image_name"];
    $post["username"] = $row["username"];
    $post["title"]    = $row["title"];
    $post["message"]  = $row["message"];
    $post["time"] = $row["time"];


        //update our repsonse JSON data
        array_push($response["posts"], $post);
    }

    // echoing JSON response
    echo json_encode($response);


} else {
    $response["success"] = 0;
    $response["message"] = "No Post Available!";
    die(json_encode($response));
}

?>

The only problem here is the post['img']. It doesn’t display an image. What other method can I try? Any help will do.
