I want to realize that an image is not allowed to be obtained, that is, not to be saved or downloaded by others. How to achieve it?

Shield the right mouse button and use script to control

<script language="JavaScript">
<!--

if (window.Event)
  document.captureEvents(Event.MOUSEUP);

function nocontextmenu()
{
event.cancelBubble = true
event.returnValue = false;

return false;
}

function norightclick(e)
{
if (window.Event)
{
  if (e.which == 2 || e.which == 3)
   return false;
}
else
  if (event.button == 2 || event.button == 3)
  {
   event.cancelBubble = true
   event.returnValue = false;
   return false;
  }

}

document.oncontextmenu = nocontextmenu; // for IE5+
document.onmousedown = norightclick; // for all others
//-->
</script>

Or like this
<script language="javascript">
  function nomenu()
  {
      return false;
  }
   
  document.oncontextmenu = nomenu;
  </script>
  Or:
  <body oncontextmenu="javascript:self.event.returnValue=false">

This is fine, but it will automatically appear on the picture to save the shortcut, you can also save the picture
Think about it for me

Do what is useless, as long as someone visits your website, you can get your picture. Your picture is not downloaded into the IE cache of others, how can others see your picture?
