Change background image

The user can change the background image of the ZoneImageLayout control using this dialog.

The dialog pop up contains:

2. Image viewer shows the pre-view thumbnail of the selected image file.

Once the right file is selected in the file explorer control, the user can press the OK button to accept the new change. This will apply the selected image as the background image of the control.

Or the user can press Cancel to avoid the changing of the background image.
