如何包含与用户数据库信息相关联的图像

我已经编写PHP2周了（它并不漂亮），但我无法找到问题的答案。我希望管理员类型的用户能够填写表单并将其发布到基本级别用户可以查看内容的页面。我已经让所有这些都像魅力一样工作，但我的困境是允许管理员用户也包含图像。也许我只是不知道要搜索什么。

以下是管理员用户页面的 php 代码和表单：

<?php
error_reporting(E_ALL & ~E_NOTICE);
session_start();
include_once("connection.php");
if (isset($_SESSION['adminid'])) {
$adminid = $_SESSION['adminid'];
$adminemail = $_SESSION['adminemail'];
if ($_POST['submit']) {
    $title = $_POST['title'];
    $deadline = $_POST['deadline'];
    $content = $_POST['content'];

        $sql_blog = "INSERT INTO blog (title, deadline, content, logoname)     VALUES    ('$title', '$deadline', '$content', '$logoname')";
        $query_blog =  mysqli_query($dbcon, $sql_blog);
        echo "<script>alert('Your inquiry has been posted')</script>";
    }
} else {
    header('Location: index.php');
    die();
}
$sql = "SELECT adminid, adminemail, adminpassword, adminname FROM admin WHERE     adminemail = '$adminemail' LIMIT 1";
$query = mysqli_query($dbcon, $sql);
if ($query) {
    $row = mysqli_fetch_row($query);
    $adminname = $row[3];
}
?>

这是基本级别用户页面的代码：（我注释掉了我希望显示管理员图像的图像块。

 <main>
  <div class="container">
    <div class="row topbuffpost">
        <h1>business inquiries</h1>
        <hr>
        <?php  
        include_once('connection.php');
        $sql = "SELECT * FROM blog ORDER BY id DESC";
        $result = mysqli_query($dbcon, $sql);
        while ($row = mysqli_fetch_array($result)) {
            $title = $row['title'];
            $content = $row['content'];
            $date = strtotime($row['deadline']);
        ?>
            <div class="col-md-4 col-lg-3">
              <div class="card hoverable">
              <!--  <div class="card-image">
                  <div class="view overlay hm-white-slight z-depth-1">
                    <img src="">
                        <a href="#">
                            <div class="mask waves-effect">
                            </div>
                        </a>
                  </div>
                 </div> -->
                    <div class="card-content">
                        <h5> <?php echo $title; ?> <br/> <h6>Deadline |<small> <?php echo date("j M, Y", $date); ?> </small> </h6></h5> <br/>
                        <p> <?php echo $content; ?> </p>
                        <div class="card-btn text-center">
                            <a href="#" class="btn btn-info blue-grey darken-2 btn-md waves-effect waves-light">Read more</a>
                            <a href="#" class="btn btn-primary btn-md waves-effect waves-light"><i class="fa fa-lightbulb-o"></i>&nbsp propose a plan</a>
                        </div>
                    </div>
              </div>
            </div>
        <?php
            }
        ?> 
    </div>
  </div>
</main>

所有这些都完美无缺，我只是无法弄清楚如何以与标题、截止日期和内容相同的方式显示图像。Youtube 也无济于事，太多过时的 php + 我编码的时间还不够长，无法真正自己解决问题。
