MYSQL, PHP, image upload/update fail

i am trying to allow users to update their profile picture using this code.

   require("../connection.php");

   $imgName = $_FILES['pic']['name']; 
   $imgTmp = $_FILES['pic']['tmp_name']; 
   $imgtype = $_FILES['pic']['type'];
   $imgSize = $_FILES['pic']['size'];

   $maxFileSize = 200000;
   $pic = "../uploads/" . $user_id . "_" . time() . $imgName;

   if ($imgSize > $maxFileSize) {
       $error = "size";
   }
   if ($imgType == "image/jpeg" || $imgType == "image/gif") {
       $error .= "";
   } else {
       $error = "type";
   }
   if (file_exists($pic)) {
       $error = "exists";
   }
   if ($error == "" && $imgName != "") {


   move_uploaded_file($imgTmp, $pic);

   mysql_query("UPDATE users SET pic = '$pic', WHERE username = '$username'");


if (!mysql_query($quer开发者_JAVA技巧y, $connect)) {
die(mysql_error());
   } else {
mysql_close($connect);
header('location:http://www.WEBSITE.co.uk/users/upload-pic-thanks.php');
}
   } else {
header("Location:edit-pic-error.php?e=".$error);
}

and it gives me this in the address bar: edit-pic-error.php?e=type, however the file i am trying to upload is .jpg, and its smaller than the 20000kb allowance.

The table in my mysql database is called 'users', and the table row is called 'pic', its Varchar, 60, allow null ticked.

The table is not being updated with the new time stamped profile picture.

Please help.

Thanks very much

$imgtype = $_FILES['pic']['type'];

if ($imgType == "image/jpeg" || $imgType == "image/gif") {

$imgType vs. $imgtype, notice the case.
