Images in a database

Ok, I had a more barebones version of this script working, but when I
tried to put it in with my larger script, it broke. I think the problem
lies somewhere in the uploading, but I'm not sure of this. Anyway,
here's what I have:

index.php
---------------------------------
<?
include("header.inc");
if (!isset($_SESSION['username']) or ($_SESSION['username'] == "Guest")) {
header ("Location: http://www.thisisfake.com/index.php");
}
dbconnect();
?>

<title>Upload</title>

<body>
<center>
<?

if($id) {

switch ($action) {

case "delete":
$data = mysql_query("SELECT id,uploader FROM files WHERE id = '$id'");
$id = mysql_result($data,0,"id");
$uploader = mysql_result($data,0,"uploader");
if ($_SESSION["username"] == $uploader || $_SESSION["level"] ==
"admin") {
mysql_query("DELETE FROM files WHERE id = '$id'");
echo "File deleted";
echo '<META HTTP-EQUIV="refresh"
content="2;URL=http://www.thisisfake.com/upload/">';
} else {echo "Invalid permissions";}
break;
default: //Echo contents if image, else send as file download
$query = "select mimetype, data from files where id = $id";
$result = mysql_query($query);

$data = mysql_result($result,0,"data");
$type = mysql_result($result,0,"mimetype");
if ($type == "image/pjeg" || $type == "image/jpeg" || $type ==
"image/x-png" || $type == "image/png" || $type == "image/gif"|| $type ==
"image/bmp") {
echo base64_decode($data);
} else {
get($id); //This send the file as a download, instead of echoing the
contents
}
break;
}
} else {

// Listing of files and the form

echo"
<form method=POST action=upload.php enctype=multipart/form-data>
<p>File to upload:<br>
<input type=file name=file>
<input type='submit' name='submit' value='Upload'>
</form>
";

//All this stuff works
echo "<p></p>";
if ($data = getInfo()) {

echo '<table border="0" align="center">
<tr bgcolor="#bad1d1">
<td>File Name</td>
<td><center>File Size</center></td>

';
for ($i=0; $i<count($data); $i++) {

$_SESSION["level"] == "admin") {
echo '<td><a

echo '</tr>
';
}
echo '</table>';
echo '<br>';
echo 'Number of files: ';
echo blobcount();
echo '<br>';
}

}
?>
</center>
</body>

I may have broken it further after the initial breaking, so if something
seems doubly broken that might be it. If you need more information just ask.

error messages, buddy, error messages. surely you're not expecting someone
to debug that line by line??

Ok, I fixed it myself, all it was was the index.php was outputting html
regardless of whether there was an image data request, so as a result
the data send included html in it, which made the image "corrupt".
