picture for gallery and menu for other galleries on the right side bar

Hi,

I have 7 galleries on one page. When I click on one gallery, I can see all the pictures of this one and I would like to have on the right side, all the other galleries so that people can access to the other galleries on that page….

So I have on a page product, 7 categories : category1, category2, category3, …, category7

If I click on category2, I see all the pictures of this category on the left side and in the right side bar, I would like to see category1, category3, …, category7 OR all the categories with category2 selected (so we can know that we are in that category).

I hope that I’m clear… Is it possible to do that? Could you help me please? Thanks in advance..
