how do I encrypt photos so they cannot be copied of off the websi.

I'm not an expert, but I did see this last night by chance:

<script language="JavaScript1.2">
if (window.Event)
document.captureEvents(Event.MOUSEUP);

function nocontextmenu() {
event.cancelBubble = true, event.returnValue = false;

return false;
}

function norightclick(e) {
if (window.Event) {
if (e.which == 2 || e.which == 3) return false;
}
else if (event.button == 2 || event.button == 3) {
event.cancelBubble = true, event.returnValue = false;
return false;
}
}

if (document.layers)
document.captureEvents(Event.MOUSEDOWN);

document.oncontextmenu = nocontextmenu;
document.onmousedown = norightclick;
document.onmouseup = norightclick;
//--></script>

If you encrypted them no-one could see them :) Presumably you're selling
photos? If so the best you can do is put your name through the photos - this
way a user can see the quality of your work but won't be able to use the
photos until they purchase them.

I agree with Jon. There is HTML you can use to sort of get around the "copy
and save-as" technique. But someone could always do a print screen of the
page your photo is on, and use Photoshop or even Paint to paste it. Then
they would simply crop out the surrounding area and voila...they have your
picture!

I would go to a program like Photoshop and create a logo. Make it slightly
opaque and a little artsy, like plastic wrap...then put this on top of each
image. People will still be able to see through the logo and see your
picture. But this way if someone steals your image, they have to do a lot of
work to get rid of your mark.

Of course, if you are doing something like putting up a picture of your kid
and hoping no one spreads it around the internet, you would have to use the
HTML and hope no one does a "print screen".

I have a bridge to sell you. Contact me offlist, please. I'll send you
copies of all images protected with this.

Add the following to your image tags:

<img src="someimage.jpg" nocopy="true">

Okay, I just got tired of people asking this question every day without
reading the voluminous answers already posted.

Why use print screen??

That's right. To be standards compliant, you'd have to use this markup -

<img src="someimage.jpg" nocopy="fat-chance">

Being new to this discussion group, I figured it would be helpful. I saw
something last night that I thought would be useful. I prefaced it by
stating that I was not an expert. I don't think comments like this help
anyone, and it is much less than I would expect from someone MS has labelled
as an expert. Where's the "professional" in pithy comments such as these?
Not very well done of you...

Okay, let me explain it to you. This question is posted about 2 or 3 times a
day, and receives about a dozen replies each time. All you had to do was
look for it. Instead, you repeated it, which means that everyone has to
repeat their answers a dozen times again. The first thing you want to do
when using a newsgroup is to look for an answer to your question. After
all, there aren't THAT many different problems out there. And we're sick to
death of having to re-answer that particular question. If you had been here
for 7 years, and had to answer this same question every day for people that
don't bother to look first, wouldn't you be a bit irritated?

It isn't possible to prevent image copying. Period. And if some well-meaning
newbie, who hasn't learned to speak without knowledge, tells you otherwise,
ignore them.

If you're new to the group, I'd suggest you read the hundreds of
previous messages on this topic BEFORE responding. This literally comes
up daily, and those of us who read and contribute to the group regularly
get very tired of seeing this request. Before posting suggestions, it
is advisable to understand the problem and whether the proposed solution
is feasible.

Will the script you pposted stop right clciks? Yes, IF the user hasn't
disabled Javascript. Otherwise, No.

Will the script do anything to protect the imags - an emphaic No.

Am I an exppert? No. And I don;t claim to be.

Do I post without researching? also No.

What "regular" users seem to forget about these things is that a lot of
"basic/novice" users use them - hoping and praying someone can help them
solve something. Therefore, perhaps thinking our problem is new and not
necessarily one that's been discussed before, or not necessarily
understanding someone else's answer is the same as the one they need, etc.
Jaded is never useful, no matter how tiresome a question is. If you're a
person who's out here to help, give it with the spirit of helping, not
insulting. You never know if you're going to run into working with someone
or having to refer someone, etc. Leaving a sour impression does nothing for
a person's credibility, whether they are FP intelligent or not. Sometimes a
basic solution can solve the problem. I know that the general public doesn't
understand much about how to trick themselves around getting an image, so the
thing I posted is at the least a deterrent to novices. It's a start, and a
legitime one. In any case, insults from a 'professional' are just plain rude
and really aren't necessary - that's my point - not that my answer was
right/wrong.

I say again, that's fine, but RUDENESS isn't necessary. Adding an insult to
rudeness just shows a lack of personal integrity as far as I'm concerned.
I'm a novice user. I posted a question, and I did look through the WHOLE
thing before I posted. That doesn't mean that you can't supply more than
just the basic it can't be done. It can be done - to most novice users!
That's the point! Just because you may be an expert doesn't mean the general
public is, and you can at least deter them. Remember, in all your vast
knowledge, that sometimes too much knowledge is not a good thing - you forget
the basics. And offering one option and telling someone something is fact is
not what I did. Your irritation with the question has gotten the best of you.

This question always makes me laugh because the very first thing you need to
do to become an expert in this business is to be able to say "don't put them
on the web" in response to "how do I protect my images"

I think it's a very legimate question and that right click javascript has
probably saved a few images from being snagged. Try this - put an image up
on the web with a no right click javascript then ask your wife/girlfriend
(assuming she's not in the business but can use a PC) to save it. Bet she
won't be able to - most users have no clue what a cache is much less how to
find an image in there.

Most of this is an ego issue - people assume because they put something on
the web it's so good other can't wait to "steal" it. In most cases this is
nonsense - there's some people out there who really do have the talent to
produce an image that's worth stealing. Those few will make their living
selling their work and will have figured out how to put their name across
the image. For everyone else get over it - your pictures are not good enough
to "steal" :)

My issue was not with her ignorance of the technology. That's what we're
here for. My issue was with her not bothering to read and see if the
question was asked and answered. That is not something that requires any
technical expertise, just common sense and compassion (for those who have to
re-answer it every day).

You admit you're a novice user. You admit that I'm an expert. Yet, you say
that you know better than I do about security when it comes to miages. You
say "a little security is enough." That is a statement of a novice. There is
no more such a thing as "a little security" as there is such a thing as
being "a little pregnant." Security is one of those things that either is,
or is not. Would you put a sign on your front door proclaiming that you had
an alarm system without having one? Why, it would stop SOME people from
trying to break in. Isn't that good enough?

And, as I (and many others) have been repeating this stuff over and over for
years, I'm done. If you want to find out more, just read this newsgroup.
Like you should have to begin with. Rudeness goes 2 ways. Asking a question
that you could simply have read the answer to, and expecting people who help
others out of the goodness of their hearts, to re-write their answers for
you is demanding more of the people that help you than you demand of
yourself. And that is certainly rude.

Excellent reply!
