There are various levels of answers to this question. When I say levels, I
mean levels of technical sophistication of the person developing the site
and the person trying to copy the images.

Disabling "right click" is easy and will be enough to disable people that
know very little or nothing about HTML.

Another technique is to make the image the background and put another image
on top of it (or something such as that). Look at:

http://us.imdb.com

Find an actor or actress with photos. Try to copy the photo; you won't get
it. For example, look at:

http://us.imdb.com/gallery/granitz/1161/Events/1161/mcgowan_rose10?path=pgallery&path_key=McGowan,%20Rose

There are probably plenty of guys that want to copy it. (I think there was a
more revealing image of her in IMDB.com but I don't see it now.) It can be
copied by looking at the HTML source and finding the address of the image.
So that technique provides some protection but not total.

The most sophisticated solution requires a lot of highly technical
programming but would require nearly as much technical programming to get
around. I don't know if there is an equivalent solution for Unix/Linux
however; the Windows solution only works for Windows. It involves use of an
ActiveX control to show the image. The ActiveX control would intercept
Windows GDI functions, and would have to be sophisticated enough to know
what images to protect and which images not to protect. Also the solutions
depend on the version of Windows.

I have seen a couple of discussions of doing such a thing. There are a
couple of versions around somewhere available for purchase. One place where
the solution was discussed is in codeguru.com and the other is
Experts-Exchange.com. The programmers asking about how to do it was going to
make it available for free, but the programmer using codeguru.com was told
by his employer that he could not. I can probably get in touch with that
programmer if anyone is interested in asking if the software is available
for purchase. As far as I know, the programmer using Experts-Exchange.com
never did make the software available (for free?).
