$sitetitle = file_get_contents("data/settings/title.dat");
//Get the page-data
$filetoread = $_GET['file'];
$album = $_GET['album'];
$blogpost = $_GET['blogpost'];
$cat = $_GET['cat'];
if (($filetoread) && (file_exists("data/content/$filetoread"))) {
include "data/content/$filetoread"; }
elseif ($album) {
$title = $album; }
elseif ($blogpost) {
include("data/blog/$cat/posts/$blogpost"); }
