As you can see, when we move the mouse on description on right, then image is changing. Could anybody can help me with these? Thanks!

Answer 1

Use jQuery hover

http://jsfiddle.net/eah9bgkm/

<img id="image" src="http://placekitten.com/g/130/130" />

<ul>
    <li data-link="http://placekitten.com/g/150/150">Cat 1</li>
    <li data-link="http://placekitten.com/g/151/151">Cat 2</li>
    <li data-link="http://placekitten.com/g/152/152">Cat 3</li>
</ul>

$(document).ready(function(){
    var img = $('#image');
    $('li').hover(function(){
        img.attr('src', $(this).data('link'));
    });    
});

Just add a css class to fadein/out

Answer 2

Try this:

<div id="definition1">Definition 1</div>
<div id="definition2">Definition 2</div>
<img id="imageWrapper" src="image1.png" />

Javacript:

$("#definition1").hover(function(){
    $('#imageWrapper').attr("src", function(index, attr){
        return attr.replace("image1.png", "image2.png");
    });
}, function(){
    $('#imageWrapper').attr("src", function(index, attr){
        return attr.replace("image2.png", "image1.png");
    });
});
