image uploading help

[applebiz89]

Can anyone point out/help as to why my script is not working for uploading an image to a directory and the name of the image to the database. At the moment once I submit the form, it goes to the script page but remains blank, i look in the database and nothing has happened...I have used a similar script on another one of my sites and it has worked but I have adjusted it slightly to this one.

Here is the form

<form  action="uploadimage.php"  method="post" enctype="multipart/form-data" > 
<input type="file" name="image" /> 
<br /> 
<input type="hidden" name="MAX_FILE_SIZE" value="100000" /> 
<br /> 
<input type="submit" id="submit" value="Upload"> 

</form>  

and here is my uploadimage.php script

<?php

include "include/conn.php";

include "include/session.php";
?>

<?php


// Check to see if the type of file uploaded is a valid image type
function is_valid_type($file)
{

    $valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif");

    if (in_array($file['type'], $valid_types))
            return 1;
    return 0;
}


function showContents($array)
{
        echo "<pre>";
        print_r($array);
        echo "</pre>";
}




$TARGET_PATH = "images/";

// Get POSTed variables

$image = $_FILES['image'];


$image['name'] = mysql_real_escape_string($image['name']);


$TARGET_PATH .= $image['name'];

// Make sure all the fields from the form have inputs
if ($image['name'] == "" )
{
        $_SESSION['error'] = "All fields are required";
        header("Location: addvox.php");
        exit;
}

// Verify file is an image
if (!is_valid_type($image))
{
        $_SESSION['error'] = "You must upload a jpeg, gif, or bmp";
        header("Location: addvox.php");
        exit;
}



// move file into the directory and the path name into the database
if (move_uploaded_file($image['tmp_name'], $TARGET_PATH))
{

	$sql = "INSERT INTO images(image) VALUES ({$image['name']}) ";
    $result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error());
    header("Location: addvox.php");
    exit;
}
else
{

    $_SESSION['error'] = "Could not upload file.  Check read/write persmissions on the directory";

    exit;
}
?>

It seems to upload the image to the directory, but nothing is getting through to the database, it just remains empty
