I need like this

Answer 1

See this example:

No preloading

HTML:

<div id="big-image">
    <img src="http://lorempixel.com/400/200/sports/1/">
</div>

<div class="small-images">
    <a href="http://lorempixel.com/400/200/sports/1/"><img src="http://lorempixel.com/100/50/sports/1/"></a>
<a href="http://lorempixel.com/400/200/fashion/1/" class=""><img src="http://lorempixel.com/100/50/fashion/1/"></a>
<a href="http://lorempixel.com/400/200/city/1/"><img src="http://lorempixel.com/100/50/city/1/"></a>
</div>

Javascript (jQuery)

$(function(){
    $(".small-images a").click(function(e){
        var href = $(this).attr("href");
        $("#big-image img").attr("src", href);
        e.preventDefault();
        return false;
    });
});

Currently only 1 big image, when clicking on an A, the href of the A is copied as SRC of the big image.

If you wan't to do it without the extra DOM progressing, you can add 3 big images, and load them directly. The above solution does not preload the images, the below function will.

With preloading

HTML:

<div id="big-image">
    <img src="http://lorempixel.com/400/200/sports/1/">
    <img src="http://lorempixel.com/400/200/fashion/1/">
    <img src="http://lorempixel.com/400/200/city/1/">
</div>

<div class="small-images">
    <img src="http://lorempixel.com/100/50/sports/1/">
    <img src="http://lorempixel.com/100/50/fashion/1/">
    <img src="http://lorempixel.com/100/50/city/1/">
</div>

Javascript:

$(function(){
    $("#big-image img:eq(0)").nextAll().hide();
    $(".small-images img").click(function(e){
        var index = $(this).index();
        $("#big-image img").eq(index).show().siblings().hide();
    });
});
