Antes no lo dije, pero esto si que me funciona.
Código PHP:
<?
$result = mysql_query("SELECT * FROM gallery", $link);
echo "".mysql_result($result, 0, "titulo_gal")."";
?>
<?
$link = mysql_connect("localhost", "root");
mysql_select_db("gallery_mysql", $link);
$result2 = mysql_query("SELECT name FROM photo WHERE id_gal = '1' AND principal = '1'", $link);
while($imagenes=mysql_fetch_array($result2))
{echo'<img src="images/small/'.$imagenes['name'].'""/>';}
$result = mysql_query("SELECT * FROM gallery", $link);
echo "".mysql_result($result, 0, "titulo_gal")."";
?>
