So random, but does anyone know how to take the default desktop images off of a machine. I imagine this applies to any GNOME system (though the wallpaper management on RHEL 5.something reminds me a lot more of KDE, and it has a lot of the KDE applications...), but I'd like to get the default wallpaper off so I can use it at home. The RHEL machine is one of my work machines, but I like the wallpaper and can't find it elsewhere.
