Does anyone know how to disable the web user's ability to
download a copy of a picture you put on a web page using
FrontPage 2002?

Don't publish it to your Web.

In order to display an image in a browser the image must be downloaded
to the user's computer. Any image that can be viewed in a browser can
be saved as an image file by the user. You can make it a little more
difficult for the user to save it, but you can't prevent it.

Don't give them the page url. Stops 'em dead in thier tracks everytime.
Put <nocopy></nocopy> tags around the image.
Add the "dont_steal" attribute to the <img> tag.

Putting the no copy tags is all well and good but it won't "stop" someone
who wants the photo. It may deter some but that's all.

If you don't want it taken, use you image editor and write COPYRIGHT in big huge
letters on the image. Otherwise, stuff like disabling right-click and <nocopy>
will stop only the absolute most newbie Internet user. A good 80% of people
will know how to get your images.

Of course the problem with putting copyright info in huge letters on the
photo is that it may obscure the photo enough to keep the reader from seeing
the picture.

Being the type of person I am, I'm curious what kind of pictures people want
to post but don't want stolen. Anyone care to answer?

Yeah..... there are thousands of artists and photographers who make their living
by selling their work. Given that they are professionals, alot of their work is
really really good. So it gets grabbed up by people who use it as
page/table/cell backgrounds on other sites. They have to face that fine line of
using images of good enough quality on their sites to attract buyers or
customers, but not good enough - or have Copyrighted written on them, so others
won't use them without permission.

heh.... I was being facetious. I didn't realize that there actually is a
<nocopy> tag.

Another option is a digital watermark. Using a digital watermark, you can
mark the image as your own and register it with Digimarc. If someone were
to copy it and you wanted to pursue it (assuming you found out about it), it
would be extremely easy to identify the image as your own. Digital
watermarks are near impossible to remove. Even if you crop out large
portions of the image, the copyright can still be retrieved.

See www.digimarc.com.

I would bet the watermark could be removed using
IrfanView, or maybe even notepad

Huh? Steve, have you reviewed the Web site? I have worked with Digimarc
extensively, and digital watermarks are nearly impossible to remove. If
they are applied correctly, it would take a considerable amount of skill and
expertise to even have a slight chance of removing it.

It's even preserved after a screencap and Save As in a different format.
Interesting.

I always associated the "watermark" term with adding some sort of message or
copyright notice over the top of the image, thereby reducing it's quality.
I still think this trick is pretty effective, at least if you're trying to
sell images since it makes the original fairly useless.

How do you enforce a digimarc watermark? I mean, what's to keep me from
copying your file into my own site (other than the kids look nothing like me
<g>)? And how do you know when/if I've done it?

See http://www.jimcoaddins.com/watermark.htm. It gives a pretty good idea
of what I'm talking about.

There is no automated way to determine if the image is being used elsewhere.
However, if you do find it being used, it's extremely easy to enforce your
copyright.

Once you read the watermark, you can retrieve information on the owner of
the image. If the image is marked "not reproducable", you have legal ground
to stand on and anyone can easily grab the watermark using Digimarc's
technology.

That's a shame. I was hoping they may offer a spidering capability, or some
way of integrating with Google or some other type of thing that could look
for your images and generate a report. That'd be pretty nifty, I think.

Anyway, cool to know how it works. Thanks for the example.

I got it. The watermark is still there and easily retrievable. The cool
thing is that you had no idea it was there! If I found you using one of my
copyrighted images, it would be very easy for me to take legal action
against you, and you would not a legal leg to stand on. I would be able to
easily prove that the image was copyrighted by me and not redistributable or
reusable.
