Help with Thumbnails

Hi! I am trying to find the place where I can set the configuration to show Thumbnails under main product photo. The Thumbnails reduce the size of the main product photo also I need the stickers on the left, if I move them there it will create 2 columns.

I would like to do it using integrated configuration is possible, not CSS code.

You can see how it looks now

It would probably be best if you found documentation and/or contacted Alex Branding directly since they are the developers of the theme.
