placing wow_interface_art

[Cloudykitty]

I downloaded this file for blizzard artwork..
http://us.media.blizzard.com/wow/int...erface_art.zip (Art Work)

I would like to be able to use some of the images but have no idea where to unzip the information contained in the download .

I want to use sexy map addon in creating my own map but don't know where to place the artwork folder so that i can get to the texture path.

i found XnConvert that converts the blp images to tga and back again so that if i edit i can use in wow.. problem is no idea where to place..

if anyone understands what i am trying to say please help....
