Nextgen – Galleries and thumbnails simulatanously

Hello!

I’m using Nextgen Gallery version 2.0.65.
I have my albums/galleries displayed in the sidebar with the help from a short code. When I click on a gallery, the sidebar is replaced by the corresponding thumbnails, what is standard behavior.

What I would like to accomplish, is that when I click on a gallery in the sidebar, the thumbnails are displayed in the main page(instead of in the sidebar), and that the sidebars galleries remain as galleries(doesn’t turn into thumbnails).

Any help will be appreciated.

All the best, cheers!
