Customizing the Remote Access Pages
From MediaSmartServerWiki
When you access your server over the internet, the first screen you are presented with a picture of someone else’s family. Modifying these images is fairly straightforward and can be achieved with either a simple cut and paste job from paint, or by installing the WHS Customizer Add-In.
If you are editing manually, you just need to replace or edit the following files on the server:
C:\Inetpub\home\images\i_landingpage_main.png
and
C:\Inetpub\remote\images\i_default_photo.png[1]
