I hate right-click banned sites for one reason 
only -- I have a dial-up modem. Very often will I 
stop a huge page loading (or very often the page 
won't load completely) and right-click on the 
images in order to load them individually. I'd 
much prefer that people just watermark than do 
ban the right click.

I will say however that I don't think I've 
noticed this with rubberslug galleries -- mostly 
because they load pretty well and don't have so 
many images per page.
