[Plugin: NextGEN Gallery] Trouble with lightbox

Hello,

i use this gallery first time. I have install NextGEN Gallery 1.2.1 and LightBox 2.0.2 (http://www.4mj.it/lightbox-js-v20-wordpress/).
Now i have all install without problems, but if i use it, it makes trouble on my page.

If i use this codes in my posts:

[ gallery=1 ]
[ nggallery id=1 ]

Then it makes problem. The LightBox shows on the front of page without an image. But i have 7 images uploaded. See here: http://www.metincelik.de/esma/145-nisan-2009.html

Can anyone help me, please?

thx & greetz
