Two Columns with NG Gallery and Text Side by Side

Hi,

I’m using NG Gallery to show sample portfolio images in my website;

https://www.parabolastudio.com/portfolio/

There are two different posts on the page with an nggallery shortcode [nggallery id=x] and description in each page.

I’d like to make the image thumbnails and texts show side by side, not the texts below the thumbnails.

How could I do this?

Thank you in advance!
