Sortable Table Images

So I have a php/mySQL sortable table, but to the right of the links that sort the table i want little arrow graphics that show the user whether they are sorting the list by ASC or DESC where and how do i put the code for the graphics

thanks kevin

here is the php code:

<?php

// This script retrieves all the records from the model_list table.
// This script paginates the query results.
// This script sorts the query results.

require_once (); // Connect to the db.

// Number of records to show per page:
$display = 10;

// Determine how many pages there are.
if (isset($_GET[‘np’])) { // Already been determined.

$num_pages = $_GET[‘np’];

} else { // Need to determine.

// Count the number of records
$query = “SELECT COUNT(*) FROM model_list ORDER BY model_name ASC”;
$result = mysql_query ($query);
$row = mysql_fetch_array ($result, MYSQL_NUM);
$num_records = $row[0];

// Calculate the number of pages.
if ($num_records > $display) { // More than 1 page.
$num_pages = ceil ($num_records/$display);
} else {
$num_pages = 1;
}

} // End of np IF.

// Determine where in the database to start returning results.
if (isset($_GET[‘s’])) {
$start = $_GET[‘s’];
} else {
$start = 0;
}

//Default column links.

//Determine the sorting order
if (isset($_GET[‘sort’])) {

//Use existing sorting order.

switch ($_GET[‘sort’]) {

case ‘mna’:
