I'm brand new to WordPress websites, switching over from my very static (but user friendly) iWeb site. I chose the Nicolas theme because I liked the slider integrated into the front page. However, I cannot figure out how to place my images in the slider. When I click "add new slider," it asks for a "name" and a "value." I don't understand what "value" means, or why there isn't a image uploading option to place pictures into the slider. Any insight/guidance on how I can get my pictures rotating in this slider would be greatly appreciated.
