I have images that I need to prevent the user from doing a right click and
selecting "Save Picture As"? How can I do this?

you cannot prevent it. you may take steps to make it more difficult but
there are always ways to get the picture. i'd suggest you copyright the
picture. if this doesn't work for you, handle the oncontextmenu event from
javascript which fires off when the right mouse button is clicked. there
won't be a menu so the picture won't be saved....for the most part.

a savvy user can always capture the entire screen and use paint to obtain
just the required pieces.

Or you can just turn off JavaScript and the context menu will always be
shown. Or you can view the document source, get the image URLs and navigate
the browser to them directly. Point being that it is not hard to get around
the programmatic restrictions.

In the end, it may be more trouble then it is worth to restrict the
downloading of the images. What you might do is place some kind of
watermark on the images to make it more difficult for the person to use on a
non-legitimate way.

Any web site which has right-click disabled is a sign of an amateur web
site. If your clients don't mind having that reputation, go right ahead.
There is simply no way to prevent pictures from being downloaded by the
browser. That is, after all, what a browser does. If you see it in the page,
it's already on your computer.

well i wouldn't go as far as saying it is amateur, i think that is overly
hash. OP probably needs to protect his IP thru copyrighting, that will give
some legal recourse, or the watermark is a good idea, although a good dose
of paintshop pro will remove the watermark.

No can do. You can make it so the the majority of users cannot save it
(ie, through JavaScript as was mentioned), but if someone really wants to
save it, they will.

Think about it: You have to transfer the picture to the web browser so it
can be displayed, right? In that case it already is: 1) in the client
computer's memory, and 2) probably in a cache locally too.

If you want to see how else you can try to protect your picture post here.

Yes, digital watermarks are the only possible means to any real kind of
protection. Of course, it doesn't stop someone from copying the images, but
it does make it possible to track them down and prosecute.

Here is solutions you might try.

1. Javaapplet showing the pictures.
2. Flash to show the pictures.

Just for giggles, I will often check out "image stopper" attempts.
Very few cannot be easily outwitted. If you are only interested in
keeping "honest people honest" then go for it. Otherwise, just figure
any image that you put on the web can be downloaded and work around
it. If you are putting copies of images you want money for, try
putting a complex watermark on the image. Also, make the image very
low resolution. It will keep people from being able to use it for
much, plus saves download time. The Flash option might work better
than the Java applet, but even then, there is always Alt-Print-Screen.

Two words.....
screen capture

If you can see it, it is available to "steal".
