Theme edit to add slider

Hey guys,

so i’m new to WP and trying to figure it out…tried searching but couldn’t find any answers…. to make this short, i would like to replace the static image on my free theme (unconditional) to a slider. Looked through all the settings within the theme and widgets and don’t see any options of this. So I’ve created a child theme and thought i was on the right track, but i’m afraid i don’t know where to go from here…

you can see this at http://www.wallbuildercustoms.com/index1

please let me know what info you may need.

thanks in advance for any help.

Joel
