How can I change an image, displayed when client computer is locked remotely?

Version 9 and 8 by default uses a graphics image instead of text notification, used in previous versions. To replace an image or edit it, please open the following file:
C:\Program Files\Net Control 2\locked.jpg
in any graphic editor, for example Windows Paint, edit it and save using the path above.

For versions 7.xx or below:
