I used Dig marc for a while, back when I did more original
graphics for
a side web page business. I was able to locate exactly one
"theft" of an
image and decided it probably wasn't worth the expense.

Probably the only way to protect an image is not to publish
it to the
web... even pictures from Worth1000, with their name
scrawled across the
bottom, can be altered/photoshopped to eliminate
the'branding' with a
little time and care. My final solution was to charge
clients more for
original graphics and write them off, so to speak.

"Most people don't realize how important librarians
are. I ran across a
book recently which suggested that the peace and prosperity
of a culture
was solely related to how many librarians it contained.
Possibly a
slight overstatement. But a culture that doesn't value its
librarians
doesn't value ideas and without ideas, well, where are
we?" Neil Gaiman

Unfortunately, once an image is viewed on a user's computer,
it's
already downloaded to their machine and in their possession
- you
can't *prevent* the downloading (and use) of that image,
since they
had to download it to see it. You can slow them down and
make it more
difficult for the casual user to quickly grab the image off
of your
pages, but that's about it. The no right-click javascript is
one way
to keep most people from casually stealing your images. I
remember
hearing about "digimarks" a while back - invisible
watermarks that
some software (maybe Photoshop?) could insert into your
image before
you upload it to your server. No visible watermarking, but
you could
search on the digimark information and find anyone who is
using your
images on their websites. I don't know what the current
state is on
that technology! Good luck!
