Change image display on listings page

Hello,

I’m very new to the theme. Is there a way to change or design the photo slider on listing pages? It doesnt look like i’m able to edt the GD Detal Top Section of Listin pages ad I’m really not a fan of the borderless pictures next to each other.

Also How do I include the map above the listing name and address in the same GD Detal Top Section of Listin pages?

Thank you.
