PhotoPress and NextGen Gallery

Hi,
I am trying to work with your templater and prepare my new web site. I would like to post some photos only in article. If I put NextGen gallery in to artice and open it from main page, clucking on picture it is ok and image will open and i can go to next one. But if I click and open article first and then click on Picture I am transfered back to main page and no gallery is opend. Do not know how to solve it, should i use diferent Gallery?

Thank you.
