While the user is logged in, i want it to keep my session id when I move from link to link. But its loosing it

When clicking on the link it first goes to this part of code

 

<?

session_name ('YourVisitID');

ini_set('session.use_cookies', 0); // Don't use cookies.

session_start();

$session = session_name('YourVisitID');

include ('./includes/header.html');

 

?>

 

<html> 

<meta http-equiv="refresh" 

content="0;url=showpage.php?page=1&YourVisitID=".SID.> 

</html>

 

Then that redirects to this code

 

<?

session_name ('YourVisitID');

ini_set('session.use_cookies', 0); // Don't use cookies.

$session = session_name('YourVisitID');

session_start();

 

include ('./includes/header.html');

?>

 

 

<html>

 

 

<center>

<h2>Becky's Photo Gallery</h2>

Please, click each thumbnail image to see more details. Thanks.

#### Resizing Function #########

function imageResize($width, $height, $target) { 

if ($width > $height) { 

$percentage = ($target / $width); 

} 

else { 

$percentage = ($target / $height); 

} 

$width = round($width * $percentage); 

$height = round($height * $percentage); 

return "width=\"$width\" height=\"$height\""; 

}

echo ("<table border=1 cellpadding=5 cellspacing=5><tr>"); 

$page=$_GET['page']; 

 

  $mydir = dir('./data'); # read every file in the directory of "data"

  while(($file = $mydir->read()) !== false) {

  if (stristr($file, "JPG")){ # only JPG files

$total++; 

if ($total>28*($page-1) && $total<=28*($page)){

$count++; 

$mysize = getimagesize("./data/$file");

echo ("<td width=100 align=center valign=middle><a href=./view/show.php?id=$total>"); 

echo ("<img src=./data/$file "); 

echo (imageResize($mysize[0], $mysize[1], 100)); # thumbnail size 100 pixel

echo (" border=0></a></td>"); 

if ($count>6){

echo ("</tr><tr>"); 

$count=0; 

}

} #total<15

}

  }

 

# fill out the blank cells with *

}

}

# prepare the navigation menu for more images/pages

 

$n=((int)($total/29))+1;

}

}

 

?>

<?php

ini_set('session.use_cookies', 0);

session_start(); // Start the session.

 

?>

}

  } 

# set the current image, and the previous and the next one by number (+/-)

$last=$count; 

$previous=$current-1; 

$next=$current+1; 

if ($current==1){$previous=$last;} # avoid the minus number

if ($current==$last){$next=1;} # avoid the out of range number 

# get the image size into an array 

$mysize = getimagesize("$filename"); 

echo ("<a href=show.php?id=".$previous.">Previous Image</a> | ");

if ($mysize[0]>600 && $mysize[1]>600){ # width AND height are greater than 600 pixel

echo (imageResize($mysize[0], $mysize[1], 600)); # resize upto 600 pixel

} 

echo ("border=0></a>"); 

echo ("<p>");  ?> 

<form action=show.php> Change Slide Show Interval: 

<SELECT NAME="interval">
