//$file_type = $HTTP_POST_FILES['userfile']['type'];

$image = substr($file_name, -4); // checks file.ext
echo "file type: $image<br>";
if (!($image == ".gif"))or !($image == ".jpg")){
$error_msg = "Please supply a gif or jpeg file.<br>";
echo "$error_msg";
}

You need to use AND insted of OR

if (!($image == ".gif"))or !($image == ".jpg")){

if (!($image == ".gif")) AND !($image == ".jpg")){
