The BackgroundImageRotator Stack stack makes it possible to create full screen, responsive background image slide shows with loads of options to tailor it to your needs.
Nineteen different animations, autoplay, navigation dots, pause/play buttons, an overlay (color, image and/or text)… The number of options is too big to mention them all here. If you are interested in spicing up your site with a neat slide show in the background, I suggest you visit the product page for all details. Here you’ll also find a link to a demo site that shows the numerous possibilities of this stack.
Is the background in the theme of your choice largely covered with non-transparent blocks? No problem, I also released a free stack for that: the SetOpacity Stack. With this stack you can add opacity to the background color of elements that have their (solid) color defined by the theme.
