What are some ways of protecting images online. A friend wanted some advice on her website. Someone told her:

Code:
I would also drop the watermark from the images. Web images are low-res enough that no one is really going to be able to do anything with them if they copy them. And watermarks are pretty easily removed, so folks can "steal" them if they want anyway.


Here are some examples of the watermarks he was talking about

She is worried about someone possibly stealing her art. Any advice or comments?

Photoshop has a demo of a filter which embeds copyright information into an image.

I don't know anything more about it though....

There are no real methods of protecting images, unfortunately. However watermarking is a sure way to turn people off stealing your images Very Happy. I think your friend is reasonable in watermarking her work, since that's some pretty good artwork. If she doesn't mind the watermarking, then I think she should stick with it. As to removing the watermark, I don't think it's possible without destroying/damaging part of the image...

I'd beg to differ - 15 mins in Photoshop and that would be gone without trace

Maybe it's very late to post a reply but there is a script that will help you to protect your images!! I can't find any way to copy a image if I have used this script. The ownly problem is that this script will block your right mouse click totally. Confused

Code:

<SCRIPT language="JavaScript1.1">
function right(e) {
if (navigator.appName == 'Netscape' &&
(e.which == 3 || e.which == 2))
return false;
else if (navigator.appName == 'Microsoft Internet Explorer' &&
(event.button == 2 || event.button == 3)) {
alert("Your alert here!!");
return false;
}
return true;
}

document.onmousedown=right;
document.onmouseup=right;
if (document.layers) window.captureEvents(Event.MOUSEDOWN);
if (document.layers) window.captureEvents(Event.MOUSEUP);
window.onmousedown=right;
window.onmouseup=right;
//  End -->
</SCRIPT>

Any Javascript can be bypassed: simply turn off Javascript in your browser Wink

my keyboard also has a right-click menu button, left click the images and hit the menu button and the right-click menu opens, then do what's needed Smile

Yes that's right, maybe there is a way to block it without that damn alert. That would make a lot of things better. Wink

Even with that its still possible to save the images its not hard at all so you should probably protect them another way.
