Showing random divs using Jquery
<p>I have a list if divs which contain images. I need to randomly show 4 of these each time the page loads. Here's the code I'm starting with.</p>

<pre><code>&lt;div class="Image"&gt;&lt;img src="/image1.jpg"&gt;&lt;/div&gt;
&lt;div class="Image"&gt;&lt;img src="/image2.jpg"&gt;&lt;/div&gt;
&lt;div class="Image"&gt;&lt;img src="/image3.jpg"&gt;&lt;/div&gt;
&lt;div class="Image"&gt;&lt;img src="/image4.jpg"&gt;&lt;/div&gt;
&lt;div class="Image"&gt;&lt;img src="/image5.jpg"&gt;&lt;/div&gt;
&lt;div class="Image"&gt;&lt;img src="/image6.jpg"&gt;&lt;/div&gt;
&lt;div class="Image"&gt;&lt;img src="/image7.jpg"&gt;&lt;/div&gt;
</code></pre>

<p>All of these will start as display:none, I'd like to take 4 of the divs at random and set them to display:block. I'm assuming I need to use "Math.random()" in there somewhere but not sure how JQuery does this. Any pointers would be appreciated.</p>
