[Design-team] Attribution question

Hi

if we want to use a Spherical Cox wallpaper as the basis for a Spin 
wallpaper, what is the correct way to attribute the original authors? 
(file:///usr/share/backgrounds/spherical-cow/default/standard/spherical-cow.png 
)

Similarly, we may base a desktop KDE theme on a previous one, a KSplash 
theme using some standard KDE / Fedora icons

thanks

Brendan
