KDE 4 images/themes location?

I wonder, where KDE4 keeps it wallpapers, theme graphic files etc?
I can’t seem to find them. File names does not respond the name which is written in “application settings”.

In /usr/share

drill down that dir and you will find
/emoticons
/icons
/themes
/wallpapers

Oh yes, thanks.
Kde3 was keeping them in /opt/kde3 and in different way. That is why I couldn’t find by filename.

thanks again
