Set clickable fullscreen background images for single posts and pages. Compatible with all major browsers and very easy to install.
First check if your theme has a boxed layout (like TwentyTen, the default WP theme) or if your theme has a fullwidth layout. If it has a fullwidth layout you may want to use semi-transparent background images for the content area so that the vistors can see the fullwidth background images. You can use the z-index option in inoplugs_background_plugin.php to adjust the background layer. If the background image doesn't show up increase the value from -999 to -1. If that doesn't help try 0 or a positive value like 1.
