This is what I used when I wanted to do something like that… a long time ago! =P
$sql = "SELECT image FROM table WHERE cond ORDER BY xxxx DESC LIMIT 5";
$result = mysqli_query($db,$sql);
while($arraySomething = mysqli_fetch_array($result))
{
echo "<img src="https://stackoverflow.com/questions/13214602/php/imgView.php?imgId=".$arraySomething."" />";
}
