Set Featured Image

Hey Guys,

I am trying to set additonal featured images for my slider on my home page. Well when I click on the link the box pops up but no images from my library show up. Any suggestions?

I am currently using the “BigBang” theme. I have tried the add_theme_support(‘post-thumbnails’); in the functions file but it doesnt work. In fact the theme already had this correction from a search post I found.

Thanks
