About this action
This is a simple example of the Background Slideshow action.
Simply attach the action to a page, select up to 10 images to display in the page background and finally set the display and fade times for the slideshow.
Try resizing the browser window and notice how the background image flexes to fit the available space.
Because the background images are actually held in their own layer above the page background all content has to sit above this. Make sure your content is set to a layer and you should be OK.
