How do I install a gtk theme?

Question

You'd think this would be a bit more obvious, but I've been been googling for 45 minutes without anything clear about how to do this.

I've tried installing gnome-art .. but it doesn't have any way to install a theme I downloaded from the internet. The appearance applet doesn't let me install the theme either.

(the theme is murreza for the murrine engine)

Answer 1

Head over to Appearance preferences from Administration->Preferences->Appearance Menu. Now, drag and drop .tgz\.tar.gz file. Else, click on the Install button in Appearance Preferences and navigate to the location where the theme is installed.
