Would this be possible .... ?

I'm not sure if anyone knows of a way to do it, but is it possible that I could alter a web page to have a picture appear / disappear at pre-set times without me having to do it manually. So for example, if I'm asleep but I want this picture to appear at 3 in the morning without waking up. Any thoughts ?

Try this:

PHP Code:

---

<?php
$time = date('H:i');
$time_start = '19:00'; // Time you want the picture displayed from.
$time_end = '21:00'; // Time you want the picture to stop being displayed.
 if($time > $time_start && $time < $time_end) {
?>
<img src="path/to/picture.png">
<?php } ?>

---

That should get you started :)
