If your application will be used on more than one platform, you must create corresponding native pictures on both platforms. These pictures must be synchronized (given the same internal ID) so the correct picture will be displayed on each platform.
When you create the first native picture, be sure the Synchronize With option in the Native Picture Definition window is unmarked.
Before you save the native picture, mark the Synchronize With option. A list of pictures from the first platform will be displayed.
The pictures will automatically be given the same internal ID.
