Complicated CMS with 3 sides

Hello everyone.
Is it possible to make the buttons on the left work? I tried Finsweet CMS, but I can’t understand how to separate buttons, images, and names to left, center, and right.

Project have 3 separated sides, in left must be buttons that change an image in the center, in right must be the name of current cms image.

Preview is not working the first time, just out the preview and press it again.
Thank you!
