About LinkBacks
Hello. I've got my site up and running now (what do you think?) and have a little problem with php coding. Now, I don't know jack s**t about it but have manage to find out a little bit so far.
I have a screenshots page which has a few thuumbnails on it, and clicking on them opens up a new php page which displays the full picture. Now, I'm trying to add next and previous links above the image to move through the pics. The code I have at the moment to do this which obviously isn't working is:
As you can see, I'm a bit of a programming novice and the site is still very basic but I'd be appreciative of your help.PHP Code:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

}

<?php
$iCurr = $_GET["im"];
$iPrev = $iCurr - 1;
$iNext = $iCurr + 1;
$img_dir = './images/';
?>
<?php
/* define IMG directory */
$img_dir = './screenshots/';
echo "<div><img src=\"".$img_dir.$_GET["im"].".jpg\" /></div>";
?>
</p>

Thanks in advance.
:edit: What do you think of the way the forum integrates into the site? Does it look ok? How does it cope on other browsers?
