gallery display detail page

[mallen]

I have this dynamic gallery. It created a table of images. When I click on the image it take it to a detail page and shows the image. I can't get it to display the description. It always displays the first record's decription no matter the image that is showing. It does show the correct image. This is the gallery page:

<?php 
define('COLS', 3);
$conn = dbConnect('query');

$sql = 'SELECT * FROM images';
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($result);



$pictureid = $_GET['ID'];
$desc = $row['description'];
?>


<table>
<tr>
  		  <?php 
	// initialize cell counter outside loop
  		$pos = 0;
	do {
	//// set caption if thumbnail is same as main image
	if ($row['description'] == $row['description']) {
	$desc = $row['description'];
	}

	?>

<td><p><a href="detail.php?ID=<?php echo $row['ID']; ?>"><img src="images/thumbnails/<?php echo $row['file_name']; ?>"  /></a></p></td>
    

  

	<?php

	// increment counter after next row extracted
	$pos++;
	// if at end of row and records remain, insert tags
	if ($pos%COLS === 0 && is_array($row)) {
	echo '</tr></tr>';
	}
	}while($row = mysql_fetch_assoc($result));  // end of loop  
	// new loop to fill in final row
	while ($pos%COLS) {
	echo '<td> </td>';
	$pos++;
	}

	?>
</tr>
   
</table>

 

This is the detail page:

<?php
define('COLS', 3);
$conn = dbConnect('query');

$sql = 'SELECT * FROM images';
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($result);

$pictureid = $_GET['ID'];

//$desc = $_GET['description'];
$desc = $row['description'];
$link = $row['url'];


<img src="images/fullsize/<?php echo $pictureid; ?><?php echo '.jpg' ?>"  /> 
    <?php echo $desc; ?> <?php echo $link; ?>
