Definition and Usage

The Image control is used to display an image on a mobile device.

Note: Different wireless devices may support different image formats! For example, HTML-capable browsers support GIF files and WML-capable browsers support WBMP files.

You can specify multiple image files in the Image control and the Image control itself will choose the correct image format based on the target mobile device.
