Insert photos into calendar - php

Question

Im trying to create a calendar in php and want the selected month to display a picture (e.g. one for january, another for february and so on). I want the pictures to be extracted from a folder called 'months'. How do I do that?
This is my code:
<?php
class Calendar
{
var $events;
function Calendar($date)
{
if(empty($date)) $date = time();
define('NUM_OF_DAYS', date('t',$date));
define('CURRENT_DAY', date('j',$date));
define('CURRENT_MONTH_A', date('F',$date));
define('CURRENT_MONTH_N', date('n',$date));
define('CURRENT_YEAR', date('Y',$date));
define('START_DAY', (int) date('N', mktime(0,0,0,CURRENT_MONTH_N,1, CURRENT_YEAR)) - 1);
define('COLUMNS', 7);
define('PREV_MONTH', $this->prev_month());
define('NEXT_MONTH', $this->next_month());
$this->events = array();
}
function prev_month()
{
return mktime(0,0,0,
(CURRENT_MONTH_N == 1 ? 12 : CURRENT_MONTH_N - 1),
(checkdate((CURRENT_MONTH_N == 1 ? 12 : CURRENT_MONTH_N - 1), CURRENT_DAY, (CURRENT_MONTH_N == 1 ? CURRENT_YEAR - 1 : CURRENT_YEAR)) ? CURRENT_DAY : 1),
(CURRENT_MONTH_N == 1 ? CURRENT_YEAR - 1 : CURRENT_YEAR));
}
function next_month()
{
return mktime(0,0,0,
(CURRENT_MONTH_N == 12 ? 1 : CURRENT_MONTH_N + 1),
(checkdate((CURRENT_MONTH_N == 12 ? 1 : CURRENT_MONTH_N + 1) , CURRENT_DAY ,(CURRENT_MONTH_N == 12 ? CURRENT_YEAR + 1 : CURRENT_YEAR)) ? CURRENT_DAY : 1),
(CURRENT_MONTH_N == 12 ? CURRENT_YEAR + 1 : CURRENT_YEAR));
}
function getEvent($timestamp)
{
$event = NULL;
if(array_key_exists($timestamp, $this->events))
$event = $this->events[$timestamp];
return $event;
}
function addEvent($event, $day = CURRENT_DAY, $month = CURRENT_MONTH_N, $year = CURRENT_YEAR)
{
$timestamp = mktime(0, 0, 0, $month, $day, $year);
if(array_key_exists($timestamp, $this->events))
array_push($this->events[$timestamp], $event);
else
$this->events[$timestamp] = array($event);
}
function makeEvents()
{
if($events = $this->getEvent(mktime(0, 0, 0, CURRENT_MONTH_N, CURRENT_DAY, CURRENT_YEAR)))
foreach($events as $event) echo $event.'<br />';
}
function makeCalendar()
{
echo '<table border="1" cellspacing="4"><tr>';
echo '<td colspan="7" style="text-align:center"> <img src= \"img/months/$month.jpg\" > </td>';
echo '</tr><tr>';
echo '<td width="30"><<</td>';
echo '<td colspan="5" style="text-align:center">'.CURRENT_MONTH_A .' - '. CURRENT_YEAR.'</td>';
echo '<td width="30">>></td>';
echo '</tr><tr>';
echo '<td width="30">Mon</td>';
echo '<td width="30">Tue</td>';
echo '<td width="30">Wed</td>';
echo '<td width="30">Thu</td>';
echo '<td width="30">Fri</td>';
echo '<td width="30">Sat</td>';
echo '<td width="30">Sun</td>';
echo '</tr><tr>';
echo str_repeat('<td> </td>', START_DAY);
$rows = 1;
for($i = 1; $i <= NUM_OF_DAYS; $i++)
{
if($i == CURRENT_DAY)
echo '<td style="background-color: #C0C0C0"><strong>'.$i.'</strong></td>';
else if($event = $this->getEvent(mktime(0, 0, 0, CURRENT_MONTH_N, $i, CURRENT_YEAR)))
echo '<td style="background-color: #99CCFF">'.$i.'</td>';
else
echo '<td>'.$i.'</td>';
if((($i + START_DAY) % COLUMNS) == 0 && $i != NUM_OF_DAYS)
{
echo '</tr><tr>';
$rows++;
}
}
echo str_repeat('<td> </td>', (COLUMNS * $rows) - (NUM_OF_DAYS + START_DAY)).'</tr></table>';
}
}
$epcMonthPic = date("m", mktime(0,0,0,$mo)); //change the "F" for "m" if you want to use numbers
$epcImagePath = "/img/"; // the path to your monthly images (keep the trailing slash)
$epcImageExt = "jpg"; // the extension you'll be using for your images
echo "<img src=\"$epcImagePath$epcMonthPic.$epcImageExt\">";
$month = $_REQUEST["month"];
$cal = new Calendar($_GET['date']);
$cal->makeCalendar();
?>

In the method makeCalendar() fix line:
echo '<td colspan="7" style="text-align:center"> <img src= \"img/months/$month.jpg\" > </td>';
with:
echo '<td colspan="7" style="text-align:center"> <img src="img/months/' . CURRENT_MONTH_N . '.jpg" > </td>';
and make sure that images exists:
img/months/1.jpg
img/months/2.jpg
...
img/months/12.jpg
