Web Photo Albums
One interesting application that your Kurobox can play is to serve a web interface to view/manage your photo albums. It usually involves installing a web server, such as Apache, or Lighttpd, PHP, and a database manager, such as MySQL or SQLite.
There are several applications that can do this job; It's advised to compare the list of web album software from wikipedia to find out the one that suits you best.
Installing a web photo album software shouldn't be kurobox-specific, so the best is to follow the publisher's instructions to installing their software on your Kurobox.
