Embedding G2 into website already using URL rewrite

Hi!

Im trying to embed Gallery2 into an already existing website. This website consists of multiple pages, all of which are accessible through a menu. The different pages are stored in a database and they are called using an URL of the form www.xyz.com/page.php/234/12/23/ where the numbers redirect to the correct page.

I want to embed Gallery2 into the website, so that by clicking on certain menu entries, certain Gallery2 albums are shown. For example, if I have an menu entry "EventXY > Pictures" and I click on it, I want the website to show the corresponding album.

I already got all of this to work and a call to such an album looks like this: www.xyz.com/page.php?g2_itemId=11/234/12/23/
But there remains one problem: When showing the embedded album, I still need the "/234/12/23/" (e.g. to highlight the current menu-entry) and all the links contained within the album (e.g. clicking on a picture) have a URL of the form www.xyz.com/page.php?g2_itemId=17

How can I fix this? Is there also a solution when I use URL rewrite within G2, e.g. www.xyz.com/page.php/v/11/234/12/23/. Where the "/v/11" part is for G2 and the "/234/12/23/" part is for my website?
