ทำสไลด์จะให้ภาพสุ่มมาจากฐานข้อมูลแสดงได้ยังไงครับ มีโค้ดให้ดู

$sql = "SELECT * FROM m_slide ORDER BY rand() LIMIT 1";

echo "<li class='s3sliderImage'> <img src='Slide/".$slPic."' width='650' height='400'> <span class='top'>$sldetail</span> </li>";

<?PHP
$DBServer = "localhost";
$DBName = "edu_clinic";
$DBUsername = "root";
$DBPassword = "1234";
$conn = mysql_connect($DBServer, $DBUsername , $DBPassword ) or die("Could not connect to dbserver");
mysql_select_db($DBName,$conn);
mysql_query("SET NAMES UTF8");

	echo"<table border='0' width='100%'>";
      //<!-- Slide -->
	echo "<div id='s3slider'>";
 	echo "<ul id='s3sliderContent'>";
	$sql = "SELECT * FROM m_slide ORDER BY rand() LIMIT 5";
	$result = mysql_query($sql);
	while($row=mysql_fetch_array($result)){
		$slID = $row["id"];
		$slPic = $row["pic"];
		$sltitle = $row["title"];
		$sldetail = $row["detail"];
    //<!-- Slide 1 begin -->
    echo "<li class='s3sliderImage'> <img src='Slide/".$slPic."' width='650' height='400'> <span class='top'>$sldetail</span> </li>";
    //<!-- Slide 1 end -->
