How to upload ONLY images in database - php

Question

I want to upload ONLY pictures , in the database using php.
What I tried is,
<?php
if (isset($_POST['Upload'])) {
$con = mysql_connect("localhost", "root", "");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("iis", $con);
$image = $_FILES["product_image"]["name"];
$imageType = mysql_real_escape_string($_FILES["product_image"]["type"]);
if (substr($imageType, 0, 5) == "image") {
if (!file_exists("product_images")) {
mkdir("product_images");
}
if ($_FILES["product_image"]["error"] > 0) {
$error = "ERROR Return Code :" . $_FILES["product_image"]["error"] . "<br />";
} else {
move_uploaded_file($_FILES["product_image"]["tmp_name"], "product_images/" . $_FILES["product_image"]["name"]);
}
}
$UserName = $_SESSION['id'];
$product_image = ("product_images/" . $_FILES["product_image"]["name"]);
mysql_query("INSERT INTO `feedbackzxc` VALUES ('', '$UserName', '$product_image')");
echo "Image Uploaded!";
} else {
echo "Only images are allowed";
}
?>
But when I upload a file other than images it doesn't show the error message. How can I make it show error message if a file other than an image is uploaded?

Your else block where the message Only images are allowed is shown must be located after the if block that check this: substr($imageType,0,5) == "image"
if(substr($imageType,0,5) == "image"){
if(!file_exists("product_images"))
{
mkdir("product_images");
}
if($_FILES["product_image"]["error"] > 0)
{
$error = "ERROR Return Code :" . $_FILES["product_image"]["error"] . "<br />";
}
else
{
move_uploaded_file($_FILES["product_image"]["tmp_name"], "product_images/".
$_FILES["product_image"]["name"]);
}
}
else
{
echo "Only images are allowed";
}
