To create a banner slider, first create a unique name for your slider. The delay value determines the length of time in seconds that the banner image is visible before it slides to the next image. After a slider is created, activate it by clicking on the name. Once activated, you can edit the name or drag a banner from the "Source Banners" column into the "Selected Banners" column. Once the images have been added to the "Selected Banners," click on the save icon.
