javascript - CSS /JS to prevent dragging of ghost image?

Is there a way to prevent the user from seeing a ghost of the image they are trying to drag (not concern about security of the images, but the experience).

I've tried this which fixes the problem with the blue selection on text and images but not the ghost image:

img {
  -webkit-user-select: none;
  -khtml-user-select: none;
  -moz-user-select: none;
  -o-user-select: none;
  user-select: none;
}

(I also tried nesting the image inside a div with the same rules applied to the div). Thanks

You can set the draggable attribute to false in either the markup or JavaScript code.

// As a jQuery method: $('#myImage').attr('draggable', false);
document.getElementById('myImage').setAttribute('draggable', false);
<img id="myImage" src="http://placehold.it/150x150">
