image will be clicked automatically one time
<p>I have an image in my site:</p>

<pre><code>&lt;img src = "bird.jpg" class="main_mark"&gt;
</code></pre>

<p>I want that while the user enters the site, this image will be clicked one time automatically.</p>

<p>How can I do that? Maybe I should define something in my JavaScript code?</p>
