We will make a slider with stylized thumbnails using CSS3
The markup is very simple:
Radio Inputs
Labels with thumbnails to detect click event
Main Image
-->
<div class="slider">
    <input type="radio" name="slide_switch" id="id1"/>
    <label for="id1">
        <img src="http://thecodeplayer.com/uploads/media/3yiC6Yq.jpg" width="100"/>
    </label>
    <img src="http://thecodeplayer.com/uploads/media/3yiC6Yq.jpg"/>
    
    <!--Lets show the second image by default on page load-->
    <input type="radio" name="slide_switch" id="id2" checked="checked"/>
    <label for="id2">
        <img src="http://thecodeplayer.com/uploads/media/40Ly3VB.jpg" width="100"/>
    </label>
    <img src="http://thecodeplayer.com/uploads/media/40Ly3VB.jpg"/>
    
    <input type="radio" name="slide_switch" id="id3"/>
    <label for="id3">
        <img src="http://thecodeplayer.com/uploads/media/00kih8g.jpg" width="100"/>
    </label>
    <img src="http://thecodeplayer.com/uploads/media/00kih8g.jpg"/>
    
    <input type="radio" name="slide_switch" id="id4"/>
    <label for="id4">
        <img src="http://thecodeplayer.com/uploads/media/2rT2vdx.jpg" width="100"/>
    </label>
