</head>Step 4. Now pick one of the styles below and copy the code below it:
<style type='text/css'>
#image-gallery {display: none;}
#jquery-gallery {padding:0;margin:0;list-style: none; width: 500px;}
#jquery-gallery li {width:84px; height: 80px;background-size: 100%;-webkit-background-size: cover;-moz-background-size: cover; -o-background-size: cover;background-size: cover;margin-right: 10px; border: 3px solid #fff; outline: 1px solid #E3E3E3; margin-bottom: 10px;opacity: .5; filter:alpha(opacity=50); float: left; display: block; }
#jquery-gallery li img { position: absolute; top: 100px; left: 0px; display: none;}
#jquery-gallery li.active img { display: block; border: 3px solid #fff; outline: 1px solid #E3E3E3; width:490px; max-height: 375px;}
#jquery-gallery li.active, #jquery-gallery li:hover { outline-color: #DFDFDF; opacity: .99;filter:alpha(opacity=99);}
#gallery-caption {background: rgba(0, 0, 0, 0.3);color: #fff;font-size: 16px;font-weight: bold;left: 3px;position: absolute;text-align: center;top: 103px;width: 490px;text-transform: uppercase;}
</style>
<style type='text/css'>Note: The display: none; of the first ID (#image-gallery) is to prevent images appear with their actual size before they go inside the gallery container, this is while loading the code.
#image-gallery { display: none; }
#jquery-gallery {padding:0;margin:0;list-style: none; width: 200px; }
#jquery-gallery li {background-size: 100%;-webkit-background-size: cover;-moz-background-size: cover; -o-background-size: cover;background-size: cover;margin-right: 10px; width: 80px; height: 80px; border: 3px solid #fff; outline: 1px solid #ddd; margin-right: 10px; margin-bottom: 10px; opacity: .5;filter:alpha(opacity=50); float: left; display: block; }
#jquery-gallery li img { position: absolute; top: 0px; left: 200px; display: none; }
#jquery-gallery li.active img { display: block; width:370px; border: 3px solid #fff; outline: 1px solid #E3E3E3; }
#jquery-gallery li.active, #jquery-gallery li:hover { outline-color: #bbb; opacity: .99;filter:alpha(opacity=99);}
#gallery-caption {background: rgba(0, 0, 0, 0.3);color: #fff;font-size: 16px;font-weight: bold;text-transform: uppercase;margin: 0 -17px;position: absolute;right: 0;text-align: center;top: 3px;width: 370px;}
</style>
<script type='text/javascript'>Basically, what this script does is to look if there is any ID named "image-gallery" and get the different list items that may exist within it. These elements will be displayed as thumbnails and a function will decide what to do when they are clicked. So, each time we click on a thumbnail, the "active" class will be assigned and the thumbnail should be visible in the larger container.
//<![CDATA[
var gal = {
init : function() {
if (!document.getElementById || !document.createElement || !document.appendChild) return false;
if (document.getElementById('image-gallery')) document.getElementById('image-gallery').id = 'jquery-gallery';
var li = document.getElementById('jquery-gallery').getElementsByTagName('li');
li[0].className = 'active';
for (i=0; i<li.length; i++) {
li[i].style.backgroundImage = 'url(' + li[i].getElementsByTagName('img')[0].src + ')';
li[i].title = li[i].getElementsByTagName('img')[0].alt;
gal.addEvent(li[i],'click',function() {
var im = document.getElementById('jquery-gallery').getElementsByTagName('li');
for (j=0; j<im.length; j++) {
im[j].className = '';
}
this.className = 'active';
document.getElementById('gallery-caption').innerHTML = this.title;
});
}
},
addEvent : function(obj, type, fn) {
if (obj.addEventListener) {
obj.addEventListener(type, fn, false);
}
else if (obj.attachEvent) {
obj["e"+type+fn] = fn;
obj[type+fn] = function() { obj["e"+type+fn]( window.event ); }
obj.attachEvent("on"+type, obj[type+fn]);
}
}
}
gal.addEvent(window,'load', function() {
gal.init();
});
//]]>
</script>
<div >Note: if elements on your page overlap with this gallery, you might need to add the height declaration after the "position: relative;" The value of height depends on the size of your gallery.
<ul id="image-gallery">
<li><img src="IMAGE-URL1" /></li>
<li><img src="IMAGE-URL2" /></li>
<li><img src="IMAGE-URL3" /></li>
<li><img src="IMAGE-URL4" /></li>
<li><img src="IMAGE-URL5" /></li>
</ul>
</div>
<div >Change IMAGE-URL1 with the image URL. If you don't know how to get the address of an image, see this tutorial: How to Upload Images and Get the URL
<div >Again, here you need to replace the page-URL text with the URL of your page/post.
