如何在php中显示来自mysql的图像

Question

所以我有 PHP 代码来调用和显示来自 mysql 的产品.. 我在显示图片时遇到问题..当用户将项目添加到数据库时，（数据库如图所示）上传图片时，它存储在本地主机和数据库中的文件夹中..它将自动创建一个图片存储的随机数..那么我应该如何调用要查看的图片？排队：

img/ 是 localhost 中的文件夹。

数据库经验：

<?php 
// Run a select query to get my letest 6 items
// Connect to the MySQL database  
include "dbconnect.php"; 
$dynamicList = "";
$sql = mysql_query("SELECT * FROM product ORDER BY proDate DESC LIMIT 6");
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
	while($row = mysql_fetch_array($sql)){ 
             $proID = $row["proID"];
			 $proName = $row["proName"];
			 $proPrice = $row["proPrice"];
			 $proDate = strftime("%b %d, %Y", strtotime($row["proDate"]));
			 $dynamicList .= '

	  ';
	  
    }
} else {
	$dynamicList = "no new products";
}
mysql_close();
?>

<?php echo $dynamicList; ?>

你确定img/1.jpg下面有图片吗？您写道，图片会有一个随机数，但正如我所见，您正在使用数据库主键标识符。
