Picture As"

Can't be done. It's like asking, "How can I post a billborad and keep people
from taking pictures of it?"

You can't.
The image, once viewable on a browser, is already downloaded on the viewer's
computer. That is the nature of the internet.
There are tricks to disable the right click feature of the browser, but it
is not recommended.
If your images are so valuable, or rare, etc., then you shouldn't post them.
If your business is, say selling celebrity photos, you should
just post a small thumbnail with a watermark across it, or a very low
resolution image so that the quality is so poor no one would want it.
The reality is that you simply cannot secure any image.
This topic is posted at least several times a week.
To search for past articles, please use Google's "News" tab and then do an
advanced search within this group, (or any other group pertinent to the
question). It's also much faster and will garner many more useful responses.
HTH and Happy coding.

you can't. Read the other posts on the subject. Graphics and pics are
downloaded to the user's web cache on their hard disk everytime the site is
viewed. that is the nature of the technology.

If you're looking at it on your computer, it's on your computer. Think about
it. A computer isn't like a radio or television set, where images are
broadcast and browsers just pick them up. A browser downloads files. It has
to request a copy from the server. That's half of what it does. In many
cases, it can also display them in a graphical way. That's the other half.
Also, when you're looking at a web page in your browser, and you see a
graphic, what do you see? Pixels on your screen. What is a computer graphic?
Pixels (tiny square dots of color). If you see them on your screen, they are
already a picture on your computer. If you've never done this before, press
CTRL|PrintScreen, open Paint, and paste. What do you see? A bitmap (graphic)
of your screen. Now, save it as a file. Voila. You've just copied a graphic
from your screen.

Yes, you can secure images (to a certain extent). There is the ability to
remove the right-click feature from the website. However, you can also
create a secure pdf that doesn't allow people to print or copy or save the
actual image. Plus, I believe it doesn't allow people to you the "print
screen" command. The pdf method is the method we use when allowing customers
to view images we have created. It seems pretty secure to me.
Unfortunately, you have to pony up for Adobe Photoshop CS plus an add-on.

You can put a sign on your front door that tells people you have an alarm
system, even though you don't. Does that "secure your house (to a certain
extent)"? Answer: I suppose it does, just a wee bit, but I wouldn't want to
store anything valuable there.
Things are either secure, or not secure. Ask any online banking company.

Thank you, Kevin! People need to realize that the minute it's up on the web,
it could be open season. And just because you've spent big money on
software, there's always someone who can get around it.

#1 You can disable right click and look like an amateur. I
can disable javascript and still right click, but I don't
need to- if I can view it, there already is a copy saved on
my computer
#2 You can create a secure PDF, but I have a password
cracker for Adobe, but I don't need to use it as the 'print
screen' works perfectly fine.
#3 You don't need Adobe Photoshop to create a PDF, much less
an add on.
I'll sum it up easily for you. If you put it on the web, I
can take it if I so desire

You are right. However, the average web browser is not going to know how to
do all those things you just talked about. Plus doing any one of those
things is illegal and opens a person up for a law suit. Nothing is
fool-proof. The analogy of putting a sticker on your house saying it has an
alarm system but doesn't is wrong. This is "secure", but just like an alarm
system on a house, it can be by-passed. It is simply that the more elaborate
your security measures are, the less likely it is that someone with by-pass
them or try to. I suppose it gets down to how open or closed you want the
system. If you want everyone to have access to it, the security cannot be
too tight. So the basics on securing your images are to put a copyright and
logo on them, make some attempt to secure them, and give some legal
disclaimer about infringing on the copyright will open the viewer up to bla
bla bla dollars of a lawsuit. Will it be perfect? No. Someone will
ignore/bypass anything you do if they really want what you have.

Why is the average web browser going to want to download the pictures
anyway? Someone who is interested in lifting pictures will do so.
