I wrote a Script-fu a while back which will create a 3x3 grid layer  
based upon the dimensions of either the current layer or the image.  
The grid is created on a new layer so you can remove it or hide as  
necessary.

The command is added to the menus under "Filters->Render-Pattern->Rule  
of thirds grid" and the code for the script is located at the  
following URL:
