How can I lock(freeze) a div into a jquery application?
<p>I made a jquery application, and I want to add a watermark (a small picture in the top-left corner) to it for the free version. I'm struggling to make as hard as possible for the users to remove it using javascript. I'm loading that image into a div and position it with a high value for it's z-index property, so it's always on top.</p>

<p>So I've came up with this solution, but it isn't strong enough:</p>

<ul>
<li>a timer that adds the watermark periodicaly if it has been reemoved (doesn't works if the user makes it's own timer that removes the watermark periodicaly).</li>
</ul>

<p>Do you have any other ideeas? But not something very hard to code.</p>

<p>Thanks.</p>
