[php] optymalizacja zapytań Opcje

[Lejto]

Mam kod który pobiera mi dane do galerii zawiera on jednak sporo zapytań.
Mogę go trochę zoptymalizować?

[PHP] pobierz, plaintext 
$id = (int)$_GET['id'];
 		$liczba = 2;
 	    $id = (int)$_GET['id'];
 		$liczba = 2;
		$sql = $db->query('select * from galeria_foto where kategoria = "'.$kat.'" and id = "'.$foto.'"');
 		$row = $sql->fetch_array();
 		$numer = $row[numer];
 
		$sql = $db->query('select * from galeria_foto where kategoria = "'.$kat.'" and id = "'.$foto.'"');
    	$num = $sql->num_rows;
      	$ile = ceil($num/$liczba);
 
		if(!isset($_GET['id'])) $_GET['id'] = 0;
    	$strona = (int)$_GET['id'];
 
 
		$q = $db->query('SELECT `id` FROM `galeria_foto` WHERE `id` > "'.$foto.'" ORDER BY `id` ASC');
		$wiersz = $q->fetch_array();
 
		$quer = $db->query('SELECT `id` FROM `galeria_foto` WHERE `id` < "'.$foto.'" ORDER BY `id` DESC');
		$wiersz_2 = $quer->fetch_array();
 
 		$sql = $db->query('select * from galeria_foto where  id = "'.$foto.'"');
    	$num = $sql->num_rows;
      	$ile = ceil($num/$liczba);
 
		if(!isset($_GET['id'])) $_GET['id'] = 0;
    	$strona = (int)$_GET['id'];
 
 
		$q = $db->query('SELECT `id` FROM `galeria_foto` WHERE `id` > "'.$foto.'" ORDER BY `id` ASC');
		$wiersz = $q->fetch_array();
 
		$quer = $db->query('SELECT `id` FROM `galeria_foto` WHERE `id` < "'.$foto.'" ORDER BY `id` DESC');
		$wiersz_2 = $quer->fetch_array();
 
  		$zap = $db->query('select name,id from galeria_kategorie where id = "'.$kat.'"');
		$r = $zap->fetch_array();
