Add new comment to Problém s imagepicker

tak piše mi tam toto

$result = db_query("INSERT INTO {imagepicker} (uid, img_name, img_title, img_description, img_date) VALUES ('%d', '%s', '%s', '%s', '%s')", array($uid, $img_name, $img_title, $img_description, $date));
if ($result) {
$nextimgid = db_last_insert_id("imagepicker", 'img_id');
