This does NOT work. All disabling right-click does is keep the basic users
from stealing your images. There is NO way to prevent someone from really
wanting them from getting them unless you don't put them on the Internet.
For example, you could disable right-click and I could just go to my
Temporary Internet Files and get them from the cache or I could do a view
source on the site, find the path to the image and paste that into my
browser and get it that way or I could use the Import Site feature of
FrontPage to suck in the images etc, etc.
You can try these tricks to discourage the average person but ultimately
they're just tricks - not bullet proof. There are sites where you can
copyright/digitally watermark your images that might help but if they keep
them on their Hard Drive or print them those don't really help much either.
