[Plugin: NextGEN Gallery]different gallery in template on each different page

Hello,

i am looking for a solution about a little problem im having.
ive been asked to make a gallery in the template itself and everytime the viewer kliks another link in the menu the gallery changes to the gallery which is linked to that page so they see the pictures that have the same subject as the link

the website is https://www.mysticgarden.nl

i hope ive been clear enough! ??
