Use of Images on Buttons.
Images can be specified as local to the device or on an HTTP / FTP server, just specify the required protocol as part of your URL (file://\, HTTP:// and FTP://). Image will be scaled to the size of the button. JPEG and GIF images are only supported on WM devices. Both CE and WM support BMP files.

Switching to Other Applications
All controls are designed to be shown on top of PocketBrowser. If you require to switch to an application other than PocketBrowser you should minimize PB to ensure the buttons do not remain shown.

Screen Orientation
When the screen orientation changes, either using the ScreenOrientation tag or by rotating a device with hardware support, the command areas will automatically move and resize to fit the new layout. However the buttons themselves are not moved and in some cases this may result in them being off the screen or not in the expected position. If so they must be moved manually by detecting the ScreenOrientationEvent.
