here is an example if image.php

<?php
if (isset($_REQUEST['imageid']) AND $_REQUEST['imageid']>0) {
    $db = 'host:/var/db/mydb.fdb';
    $dbusername = 'sysdba';
    $dbpassword = 'masterkey';
    $query = "SELECT IMAGEDATA, MIME FROM IMAGES WHERE IMAGEID=".$_REQUEST['imageid'];
    $dbh = ibase_connect($db, $dbusername, $dbpassword, 'UTF8') or die('Couldn't connect DB');
    $result = ibase_query($query);   
    $data = ibase_fetch_object($result);
    if ($data)
    {
        header("Content-type: ".$data->MIME);
        ibase_blob_echo ($data->IMAGEDATA);
    }
    ibase_close($dbh);
}
?>
