so the code is what for the extra table it wont let me add in? I just need a basis, i can customize it.

I am having trouble using includes.
I have my first PHP file which contains the header and navigation.
Now I want to add content so I create a new page and when I type the Include code in it all works fine.
I want to create another layout table though but it wont let me.
I want it to look like this page http://www.davzie.com/main.php
Dreamweaver doesn\'t actually let me drag a new layout table underneath header and to the right of navigaion, any help would be hot,

Image Gallery Stops Displaying Albums Over 140 images
in PHP Coding Help
Posted
I followed a tutorial from CodeWalkers on how to create a simple image gallery which uses the file system in order to organise my images. Now I have everything working fine and I've modified the script quite a bit so it is to my liking and working all nice and dandy but I recently uploaded around 180 pictures into a folder and it just won't display the images at all. All of the other folders work fine but they are a lot less than that amount. Below is my script and links to my actual websites so that you can see what I'm talking about:
[b]The Image Gallery[/b] - [url=http://www.davzie.com/index.php?page=images]http://www.davzie.com/index.php?page=images[/url]
[b]Bulgaria 2005 (The Non Working Folder)[/b] - [url=http://www.davzie.com/index.php?page=images&nav=LOL%3EBulgaria%202005]http://www.davzie.com/index.php?page=images&nav=LOL%3EBulgaria%202005[/url]
Perhaps you could also help me understand why I have to add a "LOL" after the nav= because if I do'nt put anything there it just ceases to work. It used to work without it but then it just stopped.
[b]IMAGES.PHP[/b]

Okay and here we have:
[b]IMGSRC.PHP[/b]
[code]<?php
require_once('config.php');
$src = isset($_REQUEST['src']) ? urldecode($_REQUEST['src']) : null;
// we're using file_exists here to prevent working with remote files
if(isset($src) && file_exists($src))
{
header('Content-Type: image/jpg');
list($width, $height, $type, $attr) = getimagesize($src);
$img = imagecreatefromjpeg($src);
$lowest = min(THMBWIDTH / $width, THMBHEIGHT / $height);
if($lowest < 1)
{
$smallwidth = floor($lowest*$width);
$smallheight = floor($lowest*$height);
$tmp = imagecreatetruecolor($smallwidth, $smallheight);
imagecopyresized($tmp, $img, 0, 0, 0, 0, $smallwidth, $smallheight, $width, $height);
imagedestroy($img);
$img = $tmp;
}
imagejpeg($img, '', 100);
imagedestroy($img);
}
?> [/code]
I know that it's a huge amount of code to go through but it might be something stupidly simple that I'm not noticing because I'm not amazing at PHP and I just use it to make my website a little nicer. It's been buggered like this for a few months now and the family are nagging me to get it all back up again so that they can see the images.
Thank you all in advance,
David.
