Gallery Image Description

Site URL: http://chrysalis-raccoon-dytj.squarespace.com/gallery-1

So I created a new page and used the "Gallery" section and I'm noticing the image description is not showing up on the actual page. There seems to be an option when insert the images for a description but no option to make it viewable in the gallery grid. Is there a code or something where I can make the individual's description show up under the image in the grid?

password to page: "test"

Use this code
