I would like do this ...

Category One contains xxx subcategories ... they appear like you see on my site (done manually) and ... if I go in the next page, I would like to see the same thing, without limits of subcategories ...

I'm working to integrate the Tarique Side Bar on any page with DHTML navigation (in fact, I'm working in a FAST version of Coppermine : by the Tarique Side Bar, I would like people surf with DHTML navigation, without possibility to comment, vote ... ONLY SEE THE PICS with little requests page, but by inviting people surfing with COPPERMINE if they want to post, vote ...)
