Upload FF okej, men inte IE

Hej!

Har lite problem med att ladda upp med IE, fungera med Firefox.

<? 
	session_start(); 
	require("include/functions.php");
	require("include/settings.php");
	require("include/DBconnection.php");
?>

<form name="form1" method="post" action="" enctype="multipart/form-data">
<input type="file" name="imagefile">
<input type="submit" name="Submit" value="Submit"> 

<?

if(isset( $_POST["Submit"] ))
{
//If the Submitbutton was pressed do:
	
	if ($_FILES['imagefile']['type'] == "image/gif" || $_FILES['imagefile']['type'] == "image/jpeg" )
	{ 
		$sessionID = $_SESSION["RandomID"];
		$filename = "userimage/".$sessionID."-".$_FILES['imagefile']['name'];

		if (file_exists( $filename ) )
		{
				echo "<br>Name: ".$_FILES['imagefile']['name'].""; 
				echo "<br>Size: ".($_FILES['imagefile']['size']/1000)." Kb";
				echo "<br>Status: FILEN FINNS REDAN!"; 
		}
		else
		{
			
			$image = 
			copy ($_FILES['imagefile']['tmp_name'], "userimage/".$sessionID."-".$_FILES['imagefile']['name']) 
			or die ("Could not copy"); 

				$DB = new DBconnection($DBhost,$DBuser,$DBpass,$DBname,$status);
				addPicture( $sessionID, $filename  );
				
				$_SESSION["PictureID"] = $ID;

				echo "<br>Name: ".$_FILES['imagefile']['name'].""; 
				echo "<br>Size: ".($_FILES['imagefile']['size']/1000)." Kb";
				echo "<br>Status: Klart!";
		}
	}
	else
	{
		echo "<br><br>";
		echo "Could Not Copy, Wrong Filetype (".$_FILES['imagefile']['name'].")<br>";
	}
}
?> </form>

Får felmeddelandet:
