title: How to catch screen capture in JavaScript/jQuery
body: <p>A friend of mine asked me if it is possible to &quot;make something&quot; to avoid someone stealing her photos from her blog posts. I told her that we can try some options but at the end there's always a way to get the pictures, and that some people even take screen shots so they can have the images.</p>
  <p>Then I asked myself if the screen capture exists as an event so you can catch it using js/jQuery and hide the image. I have searched for a while now but still can't find an answer.</p>
  <p>Is this possible?</p>
