      Hi
      I work as the website designer for a graphics design studio
      in the past we have had some of our designs stolen from the site by people who have either used the right-click-save method or the alt-printscreen method
      I know there is a way to keep people from using the right-click-save method, as i have seen it on other pages

      I would like to know,
      a. how do you do that
      b. how, if you could, would you stop the alt-printscreen method
      and finally
      c. are there any other ways people might be able to steal my images, and if so, how would i stop them from doing so?

      thanks

      hey rockstar.

      In most modern browsers you can disable the right-click menu for a particular image. To do so, you can use the event handler oncontextmenu="return false;" within the IMG tag that defines your image:

      <IMG border=0 src="..." oncontextmenu="return false;">

      As for alt-printscreen you can try this but i don't think it works for IE7.

      <HEAD>
<script language="javascript">
function clearData(){
window.clipboardData.setData('text','')
}
function ccd(){
if(clipboardData){
clipboardData.clearData();
}
}
setInterval("ccd();", 1000);
</script>
</HEAD>

<body ondragstart="return false;" onselectstart="return false;"
oncontextmenu="return false;" onload="clearData();"
onblur="clearData();">

      Basicly if anyone can see it, they can and will find a way to grab it. There are hundreds of different ways to get images, browser cache, image capture software.. even the snippet tool in vista. I wouldn't waste my time implementing any of the suggestions above, but rather digital signatures or watermarks.

      Have a read up on this
      http://en.wikipedia.org/wiki/Digital_watermarking

      Some companies like digimarc have services to track other sites using your images.

      good luck,
      Drew

      yeah it seems to work for IE7 as well
      most of my images have been placed in tables as background images as well, so the "oncontextmenu=false" in the head works better as well

      im not too worried about going as far as watermarking though because we have a downloadable catalog as well, so they could just as easily download that, and the watermark will begin blocking views that our customers will need to see
      so im more of trying to slow them down than stop them

      but thanks,
      that helps me out alot
