This is a basic example of the AllWebMenus capability to use a set of 3 images for each menu item.
The following properties are used:
Item Background Image 1: Shows a fixed image on the Item's background; LEFT-aligned relative to <Background Tile Image> or <Background Image 2>.
Item Background Image 2: Shows a fixed image on the Item's background; RIGHT-aligned relative to <Background Tile Image> or <Background Image 1>.
Item Background Tile Image: Displays an image on the item's background.
For all menu items, the "Tiling Option" is set to "Tiles between them only".
