The COLORS explained:

Your message goes here.  This is where you place the text that you'd like to have appear when someone right-clicks anywhere on your page.  Substitute your text if you wish.
No Right Clicking
Powered by Homestead.
To get the 'No Right Click' code:

1. Highlight the entire code in the box with your mouse, then copy it by pressing 'Control' and 'C' at the same time.
2. Open your page in SiteBuilder and select the HTML Snippet Element.  It should appear on your page.
3. Click the 'Edit' button.  The Element Editor window should appear.
4. Click the 'Edit HTML' button.
5. Paste this code within the HTML window by pressing Control-V.
6. Edit this code according to the explanations below (The COLORS explained).

<script language=JavaScript>

var message="Your message goes here.";
function click(e) {
if (document.all) {
if (event.button == 2) {
alert(message);
return false;
}
}
if (document.layers) {
if (e.which == 3) {
alert(message);
return false;
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
</script>

Here's a script that will prevent people from stealing your images when they right-click and attempt to perform a 'Save As...'

1.  Open the page that you want to protect in SiteBuilder.
2.  Click Page Info at the top of SiteBuilder to bring up Page Properties on the right.
3.  Click on the Advanced tab.  You will see a box that says <HEAD>
4.  Paste the following line of code in the <HEAD> box:

    <body oncontextmenu="return false;">

(To copy highlight the entire code in the box with your mouse, then copy it by pressing 'Control' and 'C' at the same time.)

5.  Save and publish the page.
Alternate Instructions:

If you want to have a message appear when someone tries to right-click use this code instead.  Please note that it isn't as universal across browsers as the first code is.
