<a href="http://hobbes.weirdfish.net/strip.php?num=<?echo $num-1;?>">Back</a>

Wel can someone edit this script so the smallest number is 1 and it cant go any lower. And it cant go higher then the images i have. I want it to auto detect the last one.

To do that you would need a way to count how many images you have, so no one can edit your script to do that until they know how your images are saved.

<?
$num = $_GET['num'];
if(!isset($_GET['num']) OR $num < 1){ //If the input is less than one correct it
$num = "1";
}
?>
<img src="http://www.hobbes.weirdfish.net/strips/strip<?echo $num;?>.jpg" alt="strip<?echo $num;?>.jpg error">
<?php
//first we count the files in the strips
$files = scandir("strips");
$fileno = count($files) - 2;//ignore the . and .. entries
if($num != $fileno){//If we are on the last line dont echo a link other wise do
echo "<a href=\"http://hobbes.weirdfish.net/strip.php?num=" . $num+1 . "\">Foward</a>";
}
if($num > 1){ //check to see if the number is greater than one, if so echo the back link
echo "<a href=\"http://hobbes.weirdfish.net/strip.php?num=" . $num-1 . "\">Back</a>";
}
//other wise just dont echo anything
?>
