How to de-activate Priint Screen Button to protect Images
We are working on a Historical Website in all Flash. We know that people will copy photos in the website.
We are thinking of finding a way to de-activate the PRINT SCREEN button so that they cannot copy the photos.
The print screen button is part of the operating system. Browsers do not have access to update the operating system and therefore there is no option avbailable for someone to disable print screen from within their browser. A web page doesn't even have access to update the browser settings and is therefore two layers away from being able to disable the print screen option. Using Print Screen to take an image results in a lowering of the image quality - there are several far more effective ways of taking images that are also impossible to block.
Protect images and other web page content
Most of the solutions suggested here are merely an annoyance to anyone wanting your image...
If you want to protect the images stored on the server and in cache, consider using encrypted images that are displayed in a security applet. I'm surprised the option is not mentioned here because its been available since 1998.
If you want to further protect images from screen capture and printscreen, that solution is also available.
Of course there are workarounds to these solutions, but they have been the most secure solutions available since 1998 and it doesn't get better... no-one has comparable solutions despite their claims to the contrary.
Banks and online surveys use these solutions because they are the best available!

Why prevent copying
Why is it you don't want to share the photos with others?

it is very hard to prevent users from saving the image in the webpage,but water mark is a little useful.
One way that will work provided that you haven't already uploaded the images to the internet (once you have uploaded the image it is too late to apply the following protection effectively).
1. Locate all hard copies of the image (photos etc.) place them in a metal container outside and drop a match into the container.
2. Locate all CDs and DVDs that may have copies of the image on them and smash them scattering the resulting fragments.
3. Remove the hard drive from your computer and hit vigorously with a hammer (the bigger the hammer the better).
If you have uploaded the images onto a network of any sort (and the internet is the biggest network) then repeat the above steps for all computers attached to that network and hope that no one has a copy hidden away.
