Update Photos in subfolder?

So I have a P:\ Drive mapped to my Pictures folder on the server.

I update P:\ with another machine

I want to see the Pictures that are in all of the new Subfolder off P:\
Drive

How can I tell the Gallery to update the photos it knows about in p:\ Drive
without dropping it and re-adding it?


I have over 22,000 photos in it. It took quite a bit to import the first
time.

Thanks,
Scott<-
