Linking to Images Dynamically

[SurgeProto]

I'm trying to come up with a way to link to an image dynamically that will change every day. I created a page that displays a random image and would like to call it using

<IMG width=88 height=88 src='http://www.mydomain.com/potd.php?type=thumb2' border='0'>

I've seen other sites do this or use a similar method. However, this is not working. Has anyone tried anything like this before?

<?php
$file = file('http://www.mydomain.com/potd.php?type=thumb2');
$imgSrc = $file[0];
echo "<img src=\"$imgSrc\">";
?>

Your potd.php

// do some random stuff.. and use the $_GET['type']
{            }

echo 'http://www.mydomain.com/imgDir/'.$randomImage;

Is there any way to do the code on the main page so that it doesn't require the end user to have PHP. Anything can be on the potd.php page.
