Pierre,

I think the "sliding doors" technique requires at least two images and  
the technique is typically limited to resizing in one direction  
(either vertically or horizontally) and has to be fixed in the other  
direction based on the design of the images.  Not sure if this is a  
requirement here or not.

Our design guy did come up with a way to resize both dimensions using  
four images, but I'm not sure if he got the technique to work (it  
wasn't in relation to OpenLayers, it was some other thing he was  
working on, but it could apply).  This is a bit more complicated to  
set up (div container, two more divs inside that have to be set up  
correctly to contain the sliding doors images, and two more images to  
make the missing corners) than sliding doors.

Cheers,

Paul
