Visual KiX displays one of its logo's as default when users logon and your script is being ran.  We wanted to give companies the ability to display their own logo or picture during logon.  We made this process extremely simple.
Simply create a picture called
splash.bmp
or
splash.jpg
and copy this to your netlogon share.

Thats it! When users logon they will see the logo or picture you have placed in the netlogon share.  To go back to the default one that we offer simply remove your logo from the netlogon share and ours will come back.

Change it as often as you want it will cause no harm except loading time.
