[plugin: nextgen-gallery] How to center Description?

Hello,
I was wondering if there is a way to display the description of pictures in Nextgen gallery centered, is stead of left. The way i do it now, is to place the description this way: <P STYLE=”text-align: center;”> description </P>, but i want to do this by default. I have checked the css, but i don’t have a clue what to change to get this right.

Does anyone have an idea? I think it looks better to show the description centered, also because i use lightview.

Thanks in advance, Pieter.
