I'm of two minds about this. As a user, I find mouse-click disables 
annoying so I usually turn off JS on sites that try to use it. I 
couldn't care less about their images, but I do use my right-click menu 
for opening links in tabs and/or windows and resent having it disabled.
	OTOH, I have several professional photography clients, and I can't 
blame them for wanting to protect their livelihood. They understand that 
as long as the picture is on the screen, it's up for grabs, but neither 
do they wish to hand people their photos on a silver platter.
	My compromise is to use an image overlay: instead of disabling the 
mouseclick, load the "protected" image as a DIV background with a 1px 
transparent GIF stretched to fit exactly on top in the foreground. A 
right-click gives you the GIF instead of the photo. Dragging and 
dropping does the same.
	Mind you, I don't do this for every image on the site, only for photo 
enlargements. Those are easy to automate and the only images they're 
concerned about anyway.
