[Plugin: NextGEN Gallery] Load thumbcode from WordPress

Hello.
I’m trying to create different styles of Highslide gallery on different WordPress categories. For example, in the normal categories, i want to use the normal Highslide effect and on the one category, i want to use this: https://highslide.com/examples/gallery-thumbstrip-above.html
So, using Conditional Tags i managed to load different settings on different pages, but the problem is with the ‘a href’ tags: on the normal page i need to use class="highslide" onclick="return hs.expand(this, { slideshowGroup: %GALLERY_NAME% }) and on the different gallery page i need to use class="highslide" onclick="return hs.expand(this, miniGalleryOptions1)
How to overwrite the Nextgen Gallery variable to load my variabile from the conditional function loaded in header?
Thanks.
