How do I insert a user loaded image into a database

Try the fi=ollowing for putting in db.
<?
$img_filename=$HTTP_POST_FILES['INPUT_FILE_NAME_HERE']['temp_name'];
$img_type=$HTTP_POST_FILES['INPUT_FILE_NAME_HERE']['type']
$fp = fopen($img_filename,'r');
$content = fread($fp,filesize($img_filename));
$content = addslashes($content);
$SQL = "insert into table_name (file_blob) values ('$content')";
?>

for extracting:

<?
....connect to db table and access the row Then:...

Header(\"Content/type: $img_type\");
$content = $row[\'file_blob\'];
$content=stripslashes($content);

echo($content);
die();
?>
