Print protection on the Web.....

[Ranjan]

Its an application for making autorun Cd roms, it does emmbed the images & make one Exe file, but this cannot run with in browsers, You need to download it seprately. The disadvantage is, it becomes too heavy.

To my knowledge you still can print images from it, otherwise "print screen " function is always there.

I agree with Chris,
Web is a public domain, once you are on the web consider in public.
Its like having a poster of the film outside the theater, with a
notice
"No photography allowed, but you can see with your eyes"
Let me tell you that as a web devloper I have not found any full
proof ways to secure images. I personally belive that false sense
of security is bigger insecurity.

Don,

Have you considered transparent watermarking? This allows you to display the image in all its glory on the web, while retaining the original in pristine form for printing.

The picture above is an example of a technique I developed for watermarking using either PhotoShop or PaintShop Pro. The example above is obviously OTT since it incorporates three watermarks (signature, text and border) but it is for demonstration purposes only.

The techniques can be adapted easily to incorporate a company or personal logo, and provide for the application of the watermark(s) to a set of images as a batch function.

The PhotoShop technique is posted here:

Photoshop or Paint Shop Pro (I'm sure there are many others) can "screen grab" anything off the display regardless of what type of "protection" you may have instituted.

It's easier than that !!!

I had your images in 3 clicks .. without having to go on a mad search
through the temp. files

But you're right .... the little "norightclick" javascript is quite a good deterrent for a lot of users .. there are also others available which will disable the "file> save as" function .. another good deterrent which will fool most users ( but not ALL of them)

Go for a wander round the search engines for "free java scripts"

...

This is an excellent thread, with many sensible postings with perfectly correct information

Perhaps my 2 cents worth (or rather 2 euros worth) would be to add that with a full licensed version of photoshop 5.0 or 6.0 you can incorporate an electronic copyright into your final image .. . again, it's extra protection, but not full protection... your image can still be printed

or keep your pics fairly low sized for web viewing (say 640 x480 max) ... optimise them with appropriate imaging software... and then compress them just enough to still look OK on screen, but "merde" when you print them

Hello there,

I just want to say that the right click javascript function is not
a problem if you know how a computer works.

In fact, your browser downloads the image and saves it in your
temporal internet storage folder... and then it's displayed.

So you only have to go to your own windows temporal directories and
search it (it will have a strange name "$$%&$&") You can browse
with a program like ACDSee and you'll catch it.

Nevetheless, I put that protection on my page... just in case

You can go and cut and paste my html code at:

Hope it helps!
