I don't know if anyone has tried this but I attempted to cover my images with flash after realising that you can make transparent swf files.
It goes some way into protecting those beloved copyright images.

Maybe it's the wrong forum as It was all made in XX5?

Hi Anas,
Can you explain that a little more please?
When you cover an image with a transparent SWF, and the user tries to copy the image, do they get the transparent SWF instead? If so that is cool.
Also, what is contained in your SWF file? A bit of text (i.e. copyright info) or is it just a blank SWF file?
Thanks for the info.
Eric
You can do the same with a transparent PNG with text links on top.
But it still doesn't prevent screen shots or downloading of your image via Xtreme 5 / Web Designer:

There are other image downloaders can rip graphics from URLs too.
Hi Eric, the flash file contains a black pixel in the top left-hand corner and yes you only get the swf rather than the image. A transparent bitmap would be an easier option, thanks Steve.Quote:

You are completely wasting your time. There are a dozen ways to save images from a web browser that you can do nothing to prevent. The more you do to try to ‘protect’ content, the more you pointlessly risk usability and accessibility problems.Quote:

The only way to stop people using images is to give them images they won't want to use, by means of watermarking, JPEG quality loss, small size or cropping.
"Punching holes" is a good idea to protect against image downloading by any means. So the only thing left is to protect against screen grabbers.
If you don't want to put permanent watermarks as they may hide some of the graphics e.t.c., you can simply put an animated GIF with the watermarks flying all over the protected graphics. This way all screen shots will contain watermark thus being useless, and all downloaded images are mostly useless too.
So it takes at least 3 elements per image:
1. The image with punched holes.
2. The PNG of the holes on top of it.
3. The animated GIF with flying watermarks on top of them all.
It also may look much better to use Flash instead of GIF as it would allow you to make watermarks semitransparent. But, user can disable flash in the browser and then easily screen grab the image. Disabling GIF on the other hand will disable all other images so there's no trivial way to work this around.
Ingenious anti-theft measure. The only criticism I have of it is that it is very, very ugly. If you only have one or two images to protect you could create a faded, anti-aliased anigif for each one, but if you have a gallery of images this becomes impractical so you end up using a generic ugly anigif.
And of course there's nothing to stop a determined thief taking 2 or 3 screengrabs and then laying them on top of each other and removing the anigif overlays.
I'm with BobInce. The only way to stop the theft of your images is:
- to make your images such crap quality they're not worth stealing
- to not display your images at all
If there was truly a way of being able to prevent the theft of online images people like Corbis and Getty would be using it. But they too realise it's impossible so instead they use image recognition software bots to trawl the web and bombard the owner of websites using their images without authorisation with cease and desist orders plus invoices for the period of time the image has been on the owner's site. They use incredibly heavy-handed bully-boy tactics which, in many cases, work. Clearly nobody on here has that kind of muscle.
My original concern was not to protect my own art-work but rather to protect my laboured work. I was inspired by a problem I had while creating a site for a client who wanted to sell books. He instructed me to copy and paste the book images from his suppliers web site but they had played with the images so that what you saw was not what you got so I gave up and told my client to get me the images himself.Quote:

But if you also had the precious images displayed as flash then this wouldn't be a problem. Nor would it be a problem if the 'punched holes' were filled in with flash images.Quote:

Perhaps I misunderstand you, but Alt+PrnScr does work well with flash, doesn't it?Quote:

To all skeptics - it's true that there's no way to protect published content. But as far as I understand, we are talking about complicating process of it's retrieval.
Yes but the screen grab would still have your flash watermark which you can't switch off as the main image is also in flash.Quote:

“How can I stop my content being saved?” was a very common beginners' question on yesterday's web authoring mailing lists and forums. The answer arrived at then is just as relevant to Xtreme users today: You Simply Can't. You can go crazy making your life and your users' lives harder by all kinds of odd obfuscation tactics, but there are always simple ways around even for not-very-motivated would-be-thieves.
Look at the big commercial image sources, who've had years to come up with clever anti-theft methods and, having the most to lose monetarily from unauthorised copying, are infamously fierce in protecting their copyrights. Are they doing any of this? No. They just plop a watermark on and have done with it. That's the best you can do. Really.
Bob, do you see any difference between "making copying impossible" and "making copying harder"? ;)
I have already given my opinions above. The goal of "impossible" is currently impossible. The goal of "harder" is certainly possible, but at what cost of time and/or effort? There is always a trade-off between what we can and want to achieve and what we are able to achieve within the bounds of practicality. And I personally don't believe that on a dynamic and vibrant website it is worth your while mucking about with all those convoluted methods unless your images have a real and tangible value, and at that point you should seriously consider whether you want to display them on your website because, come what may, if they are good and your website risks being popular, they will be stolen.
