[Plugin: Easy FancyBox] Load Tested

But it has been tested for compatibility with WP Super Cache so if your admin worries about server load, I’d advise to use a good caching extension 😉

Anyway, if you take the latest development version from http://ww.wp.xz.cn/extend/plugins/easy-fancybox/developers/ the dynamic stylesheet has some extra response headers that facilitate browser caching.

Hope that helps 🙂
