I have a photo gallery that shows the standard options. I use tables for the whole design. The original gallery that I applied the CSS for, works without a problem. The CSS I use is for the tables.

The problem starts when the bigger preview picture opens up in a popup, is there any way that I can override certian classes and use my own. What I need is a way to override the global property such that I can contrl the popup's tables in different way and the photo gallery stays the same.
