Being able to provide just a single image for a KryptonButton is a little restrictive. Now you can provide per-state images to have a truly styled button appearance.
Office2003
When using the default Office2003 palette you only need to provide a single image for a KryptonButton control. This is because the image itself does not change during hot-tracking or when the button is being pressed. Instead the background colors change to indicate the state.
Custom Palettes
But if you are creating a custom palette then maybe you want to have your button displayed purely as a set of images. By providing a different image per-state you can achieve any look and feel you want. These images are not restricted to rectangle shapes either because you can provide a PNG that contains transparent areas.
You can see below the new properties added for specifying per-state images.

Note that if a per-state image is not provided then it will use the standard Image value instead. So you only need to actually specify the images that differ from Image.
