I am trying to list all the banners and information (link, image, etc.) in each group. I have been trying to go through banners.php in functions but it seems to have a lot of built in functions and all I need is a listing.

Example of what I need:
Banner set: #1
banner ID: banner_1
banner Image: ../includes/templates/template/images/banners/banner_1.jpg
banner Link: www.link.com

I am not asking anyone to do the work just explain to me how to use the database connection that is already there should be all I need.
