Lloks like the script is OK, but your implementation of it may be suspect. It looks as though the script can't find your files. You may need to include the document root to the file path.

Just an idea, there's no way I'm gonna wade through all that code though.

I used imageMagic instead of GD and it solved the Problem.
here is the resulting code.

<?php session_start();

 $user=$_SESSION['user'];

 $id=$_SESSION['id'];

 //include("configa.inc.php");

 // include("design.inc.php");

 include("config.php");

 $image_dir='thumb';

 $image_dir1='thumb';

 // initialization 

 $result_final = "";

 $counter = 0;

 // List of our known photo types

 $known_photo_types = array(

 'image/pjpeg' => 'jpg',

 'image/jpeg' => 'jpg',

 'image/gif' => 'gif',

 'image/bmp' => 'bmp',

 'image/x-png' => 'png');

 // Fetch the photo array sent by preupload.php

 $photos_uploaded = $_FILES['photo_filename']; 



 // Fetch the photo caption array 

 $photo_caption = $_POST['photo_caption'];

 

  // Check what is happening - remove from code when working

 echo "<br>photo_caption = ".$photo_caption;

 

 while( $counter <= count($photos_uploaded) )

 {

 if($photos_uploaded['size'][$counter] > 0)

 {

 if(!array_key_exists($photos_uploaded['type'][$counter], $known_photo_types))

 {

 $result_final .= "Erro!the file is not a photo,or More than 2MB<br />";

 }

 else{

 //create a random file name

 $rand_name = md5(time());

 $rand_name= rand(0,999999999);

 $filetype = $photos_uploaded['type'][$counter];

 

// Check what is happening - remove from code when working

 echo "<br>filetype = ".$filetype;

 

 $extention=$known_photo_types[$filetype];

 $filename=$rand_name.".".$extention;

 @mysql_query( "UPDATE login SET photo='$filename' WHERE user='$user'");

 @mysql_query( "UPDATE profile SET photos='$filename' WHERE users='$user'");

 // The orignal file

 $original_image = $photos_uploaded['tmp_name'][$counter];

 // First Create Thumbnail!

 // Thumbnail Settings

 $Config_tbwidth_wide = 100;// width of wide image

 $Config_tbheight_tall = 100;// height of tall image

 // Let's save the thumbnail

 $function_to_write = $image_dir."/".$filename ;

 exec("convert $original_image -resize {$Config_tbwidth_wide}x{$Config_tbheight_tall} -strip $function_to_write");

 

 // Check what is happening - remove from code when working

 echo "<br>Path to save thumbnail image = ".$function_to_write;

 echo "<img src=\"$function_to_write\">";

 

 // Resized image settings

 $Config_width_wide = 200; // width of wide image

 $Config_height_tall = 300; // height of tall image

 $function_to_write1 = $image_dir1."/".$filename ;

 exec("convert $original_image -resize {$Config_width_wide}x{$Config_height_tall} -strip $function_to_write1");

 

  // Check what is happening - remove from code when working

 echo "<br>Path to save thumbnail image = ".$function_to_write1;

 echo "<img src=\"$function_to_write1\">";

 

 $result_final .= "<img src='".$image_dir1. "/tb_".$filename."' /><br /><font color=green>Your  profile photo was changed</font><br /> <font size=5>To continue <a href=myprofile.php>click here</a></font><br />";

 mysql_query("INSERT INTO UPDATES SET photo='$filename',sender_id='$id'");

 }

 } $counter++;

 } // Print Result

 echo"$result_final ";  

 ?>
