I put this code in Related Wallpapers section in my wallpaper website. The below code displays me wallpapers for a specific tag (for ex:abstract,love..) but it displays me the current wallpaper and i would like to make random wallpapers in related wallpapers section. 
How to do this ?

My php code :

```
<?php
//Related wallpaper
$searchtag = $info['tag'];
$related = mysql_query("SELECT * FROM covers WHERE tag='$searchtag' LIMIT 2 ") or       die(mysql_error());
 while($info = mysql_fetch_array($related))
{ 
echo $info['name'];
Echo '<img src="thumb/'.$info['thumbflname'].'"></br>';
}
?>

```
