[Plugin: NextGEN Gallery] Thumbnails effects

Hi,

I was trying for some time to edit my thumbnails effect to the same like http://alexrabe.de/wordpress-plugins/nextgen-gallery/. If you click right on gallery on the picture you will see the effect with loading etc. Please, can someone tell me how can I have exactly the same effect for my nextgen gallery.

Thanks a lot.

Regards

Axel
