Different behaviours for 3 different browsers!!

Ok so Ive got an upload form for a recipes website im creating.
This handler works perfect in Google Chrome,
Firefox spits out no errors and no information at all is inserted into the SQL database.
IE gives a filesize error but works if no image is uploaded.

How is this possible????

<?php 
require_once("includes/connection.php"); 
require_once("includes/session.php"); 
require_once("includes/functions.php"); 
confirm_logged_in(); 

	$title = $_POST['title'];
	$smalldesc = $_POST['smalldesc'];
	$ingredients = $_POST['ingredients'];
	$method = $_POST['method'];
	$time = $_POST['time'];
	$amount = $_POST['amount'];
	$keywords = $_POST['keywords'];

?>
<?php
//check that we have a file
if((!empty($_FILES["uploaded_pic"])) && ($_FILES['uploaded_pic']['error'] == 0)) {
  //Check if the file is JPEG image and it's size is less than 350Kb
$file = basename($_FILES['uploaded_pic']['name']);
$file = "testingtxt.jpg";
list($file, $ext) = explode(".", $file);
$filename = $_POST['title'].".".$ext;
  $ext = substr($filename, strrpos($filename, '.') + 1);
  if (($ext == "jpg") && ($_FILES["uploaded_pic"]["type"] == "image/jpeg") && 
    ($_FILES["uploaded_pic"]["size"] < 350000)) {
    //Determine the path to which we want to save this file
      $newname = dirname(__FILE__).'/_images/_pic/'.$filename;
      //Check if the file with the same name is already exists on the server
      if (!file_exists($newname)) {
        //Attempt to move the uploaded file to it's new place
        if ((move_uploaded_file($_FILES['uploaded_pic']['tmp_name'],$newname))) {
		   echo "It's done! The file has been saved as: ".$newname;
		   
		   $thumb = dirname(__FILE__).'/_images/_pic/'.$_POST['title']." _thumb.".$ext;
           createThumb($newname, $thumb);
		   
		   $img = dirname(__FILE__).'/_images/_pic/'.$_POST['title'].".".$ext;
           resize($newname, $img);
		   
		   $query = "INSERT INTO recipes (
				Title, Smalldesc, Ingredients, Method, Time, Amount, Keywords, Created_at, Picture, Picturesmall
			) VALUES (
			'{$title}', '{$smalldesc}', '{$ingredients}', '{$method}', '{$time}', '{$amount}', '{$keywords}', NOW(), '/_images/_pic/$title.jpg', '/_images/_pic/$title _thumb.jpg')";
			if (mysql_query($query, $connection)) {
				header("Location: allrecipes.php");
				exit;
			} else {
					echo "<p>Recipe not entered.</p>";
					echo "<p>" . mysql_error() . "</p>";
				}
		   
        } else {
           echo "Error: A problem occurred during file upload!";
        }
      } else {
         echo "Error: File ".$_FILES["uploaded_pic"]["name"]." already exists";
      }
  } else {
     echo "Error: Only .jpg images under 350Kb are accepted for upload";
  }
} else {
	$query = "INSERT INTO recipes (
				Title, Smalldesc, Ingredients, Method, Time, Amount, Keywords, Created_at, Picture, Picturesmall
			) VALUES (
			'{$title}', '{$smalldesc}', '{$ingredients}', '{$method}', '{$time}', '{$amount}', '{$keywords}', NOW(), '/_images/_pic/1000.jpg', '/_images/_pic/1000 _thumb.jpg')";
			if (mysql_query($query, $connection)) {

				exit;
			} else {
					echo "<p>Recipe not entered.</p>";
					echo "<p>" . mysql_error() . "</p>";
				}
 echo "Error: No file uploaded";
}
?>

<?php mysql_close($connection); ?>

That's realy weird, coz the server handles the data and not the browser, it only sends the data
