Making specific directories have different backgrounds

Hi.

While I'm on a roll...

Is it possible to have different directories show a specific background all the time -- based on its path?

We work with several network drives, and it would be nice to be able to distinguish them without having to look at the title bar all the time

Thanks

I was playing with this the other day, have a read of this thread especially from the second post onwards.

Got it.
Searched for instructions just like that!
Thanks
