Winnie, it is done with javascript which detects and disables the mouse's
right click and pops up a message. People who use it are fooling themselves
(and possible others) as  any picture HAS to be downloaded on to your PC
for it to be displayed by your browser - and this is done automatically
irrespective of what the script implies; it is also quite easy to override
such a script as you can disable javascript in your browser, or use
alternative keyboard options to save images...

Some of these javascript prevent you from using ANY of the right-click menu
functions and these are in my mind an abomination; they alienate people who
genuinely need to use this menu for other purposes, and  others (e.g.
lefthanders) who may be using their mice buttons with a different
configuration.

If you do a search on one of the search engines for something like "disable
right mouse click javascript" you will find many of this type of script;
here is one of them:
<script language="JavaScript1.2">
/*
Disable right click script II (on images)- By Dynamicdrive.com

*/

var clickmessage="Right click disabled on images!"

function disableclick(e) {
if (document.all) {
    if (event.button==2||event.button==3) {
       if (event.srcElement.tagName=="IMG"){
          alert(clickmessage);
          return false;
       }
    }
}
else if (document.layers) {
    if (e.which == 3) {
       alert(clickmessage);
       return false;
    }
}
else if (document.getElementById){
    if (e.which==3&&e.target.tagName=="IMG"){
       alert(clickmessage)
       return false
    }
}

}

function associateimages(){
    for(i=0;i<document.images.length;i++)
       document.images[i].onmousedown=disableclick;
    }

    if (document.all)
       document.onmousedown=disableclick
    else if (document.getElementById)
        document.onmouseup=disableclick
    else if (document.layers)
        associateimages()
</script>

Many people ask how you can stop people downloading your images - it is a
very frequently asked question on the html authoring newsgroups: the only
sure fire way to stop them is to NOT put your images on the web in the
first place. Copyright declarations - i.e. "All images copyright Winnie
Clark 2002" - are the probably the best that you can do :-((

However, I had a case recently where a Norwegian site - whose owner was
actually VERY hot on advertising her OWN copyright, which made her actions
a real sin in my mind - decided to help herself to some of MY Cavalier
graphics and offer them to all and sundry in spite of my copyright
notices... I discovered this from seeing one on someone else's site. I
asked for them to be removed from both the sites; this was done,  but  I
got no acknowledgement or apology from either of these people.

Some graphics software actually allows you to add a copyright notice "in"
the image, and I try to remember to do this with desirable items.  You
might also look into watermarking your images for identifying ownership;
there is software available for this but don't know how effective it might
be...

And finally, if the Camelot lady told Cathy WHICH site was offering her
images, maybe it would be useful to post the details, so that other people
on the list could check if any of their Cavalier photos have been stolen too?
