building walls in RmXP

[crownsofcorruption]

Ehrm, trying not to sound too Noob, but can anyone tell me how I build nice walls (like the top view of them, not the side-view) in RmXP?
I get the walls you can see, but walls that run from the top to the bottom of the screen I make (at the moment) by putting a lot of rock up there.
Now in XP I see a link to normal wall-images, but HOW do I USE these?

This doesn't make any sense.. do you mean the auto-tile wall or something?
In that case, read Dwarra's house tutorial
