In this tutorial we will create a fullscreen gallery with jQuery. The idea is to have a thumbnail of the currently shown fullscreen image on the side that flips when navigating through the images. The big image will slide up or down depending where we are navigating to. We will add navigation controls for the mousewheel and for keys. The thumbnail will have a zoom and and a fullscreen option, making the image in the background appear in fullscreen mode or as a complete image, resized to fit in the page.

We will be using Flip!, a jQuery plugin by Lucca Manno that flips elements.

And we will also be using the jQuery Mousewheel Plugin by Brandon Aaron.

The beautiful images are by talented Polina Efremova. Visit her website and check out her profile on Behance.

Let’s get started with the markup!

The Markup

First, we will add a loading element that we want to show when the images are being loaded:

<div id="tf_loading" class="tf_loading"></div>

Then, we will create a container for all the images that will be shown in fullscreen:

<div id="tf_bg" class="tf_bg">
	<img src="images/1.jpg" alt="Image 1" longdesc="images/thumbs/1.jpg" />
	<img src="images/2.jpg" alt="Image 2" longdesc="images/thumbs/2.jpg"/>
	<img src="images/3.jpg" alt="Image 3" longdesc="images/thumbs/3.jpg"/>
	<img src="images/4.jpg" alt="Image 4" longdesc="images/thumbs/4.jpg"/>
	<img src="images/5.jpg" alt="Image 5" longdesc="images/thumbs/5.jpg"/>
	<img src="images/6.jpg" alt="Image 6" longdesc="images/thumbs/6.jpg"/>
	<div class="tf_pattern"></div>
</div>

We will use the “longdesc” attribute to indicate the path to the respective thumbnail. The last div element will server as the overlay pattern.

Next, we will add a container for the contents that are shown on the left bottom corner of the screen.

<div id="tf_content_wrapper" class="tf_content_wrapper">
	<div class="tf_content" id="content1" style="display:block;">
		<h2>Dreamer</h2>
		<p>Far far away, behind the word mountains, ... </p>
	</div>
	<div class="tf_content" id="content2">
		...
	</div>
	...
</div>

Each box with a heading will be inside of an element with the class “tf_content”.

The structure for the thumbnail image on the right side of the screen we look as follows:

<div id="tf_thumbs" class="tf_thumbs">
	<span id="tf_zoom" class="tf_zoom"></span>
	<img src="images/thumbs/1.jpg" alt="Thumb1"/>
</div>

The span will either have the class “tf_zoom” or “tf_fullscreen” depending on in which mode we are in.

And finally, we will add some elements for the navigation:

<div id="tf_next" class="tf_next"></div>
<div id="tf_prev" class="tf_prev"></div>

Let’s take a look at the style.

The CSS

After doing a simple reset to the body and html, we will define the style for the full images container:

.tf_bg{
	width:100%;
	height:100%;
	position:fixed;
	top:0px;
	left:0px;
}

The container will be fixed and occupy the whole screen. The images inside will be of absolute positioning and the real width and height will be calculated dynamically in our jQuery function:

.tf_bg img{
	position:absolute;
	top:0px;
	left:0px;
	width:100%;
	z-index: 1;
	display:none;
}

The pattern will as well be absolute and have a repeated background image:

.tf_pattern{
	position:absolute;
	width:100%;
	height:100%;
	background:transparent url(../images/pattern.png) repeat top left;
	z-index:2;
}

We will position the content absolutely, too:

.tf_content{
	position:absolute;
	bottom:50px;
	left:50px;
	z-index:10;
	display:none;
}

The heading of the content will have a different font, that we will embed using the Google Font API. We’ll come back to that later.

.tf_content h2{
	color:#fff;
	font-size:90px;
	padding:0;
	margin:0;
	font-family: 'Dancing Script', arial, serif;
	text-shadow:1px 1px 2px #000;
}

The paragraph of the content will have a repeated image as background and some nice box- and text-shadow:

.tf_content p{
	color:#fff;
	padding:0;
	margin:0;
	background:transparent url(../images/bg_content.png) repeat top left;
	padding:40px;
	width:500px;
	font-family: 'PT Sans Narrow', arial, serif;
	font-size:20px;
	line-height:25px;
	text-transform:uppercase;
	text-shadow:2px 2px 1px #000;
	-moz-box-shadow:1px 1px 5px #202020;
	-webkit-box-shadow:1px 1px 5px #202020;
	box-shadow:1px 1px 5px #202020;
	border:4px solid #fff;
}

The thumbnail container will be positioned in the middle of the screen on the right side. We accomplish that with setting the top to 50% and the top margin to negative half of its height. We will give the container a reflection, that can be seen in Webkit browsers:

.tf_thumbs{
	position:absolute;	
	z-index:12;
	right:50px;
	top:50%;
	margin-top:-79px;
	border:4px solid #fff;
	-moz-box-shadow:1px 1px 5px #202020;
	-webkit-box-shadow:1px 1px 5px #202020;
	box-shadow:1px 1px 5px #202020;	
	-webkit-box-reflect:
		below 5px
		-webkit-gradient(
			linear,
			left top,
			left bottom,
			from(transparent),
			color-stop(0.6, transparent),
			to(rgb(18, 18, 18))
		);
}
.tf_thumbs img{
	display:block;
}

The navigation elements will be placed next to the thumbnail container:

.tf_next,
.tf_prev{
	width:35px;
	height:14px;
	position:absolute;
	top:50%;
	right:320px;
	z-index:100;
	cursor:pointer;
	background:transparent url(../images/nav.png) no-repeat top left;
	opacity:0.5;
}
.tf_next{
	background-position:0px -14px;
	margin-top:80px;
}
.tf_prev{
	background-position:0px 0px;
	margin-top:-55px;
}
.tf_next:hover,
.tf_prev:hover{
	opacity:0.9;
}

The little icons for zoom and fullscreen mode will appear at the right top corner of the thumbnail:

.tf_zoom,
.tf_fullscreen{
	width:20px;
	height:20px;
	position:absolute;
	top:6px;
	right:6px;
	cursor:pointer;
	z-index:100;
	opacity:0.6;
	background:transparent url(../images/icons.png) no-repeat top left;
}
.tf_zoom{
	background-position:0px -20px;
}
.tf_fullscreen{
	background-position:0px 0px;
}
.tf_zoom:hover,
.tf_fullscreen:hover{
	opacity:0.9;
}

The loading element will be positioned in the center of the screen:

.tf_loading{
	position:fixed;
	top:50%;
	left:50%;
	margin:-30px 0px 0px -30px;
	width:60px;
	height:60px;
	background:#fff url(../images/loader.gif) no-repeat center center;
	z-index:999;
	opacity:0.7;
}

And that was all the style. Let’s take a look at the JavaScript.

The JavaScript

First, we will include the following scripts:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/jquery-ui.min.js"></script>
<script type="text/javascript" src="js/jquery.flip.js"></script>
<script type="text/javascript" src="js/jquery-mousewheel-3.0.4/jquery.mousewheel.min.js"></script>

Then, we will add the preload function for the images:

(function($) {
	$.fn.preload = function(options) {
		var opts 	= $.extend({}, $.fn.preload.defaults, options);
		o			= $.meta ? $.extend({}, opts, this.data()) : opts;
		var c		= this.length,
			l		= 0;
		return this.each(function() {
			var $i	= $(this);
			$('<img/>').load(function(i){
				++l;
				if(l == c) o.onComplete();
			}).attr('src',$i.attr('src'));	
		});
	};
	$.fn.preload.defaults = {
		onComplete	: function(){return false;}
	};
})(jQuery);

In our jQuery function, we will first cache some element and define some variables:

var $tf_bg				= $('#tf_bg'),
	$tf_bg_images		= $tf_bg.find('img'),
	$tf_bg_img			= $tf_bg_images.eq(0),
	$tf_thumbs			= $('#tf_thumbs'),
	total				= $tf_bg_images.length,
	current				= 0,
	$tf_content_wrapper	= $('#tf_content_wrapper'),
	$tf_next			= $('#tf_next'),
	$tf_prev			= $('#tf_prev'),
	$tf_loading			= $('#tf_loading');

Then, we will preload the images:

$tf_bg_images.preload({
	onComplete	: function(){
		$tf_loading.hide();
		init();
	}
});

The next function will show the first image and initialize some events:

function init(){
	//get dimentions for the image, based on the windows size
	var dim	= getImageDim($tf_bg_img);
	//set the returned values and show the image
	$tf_bg_img.css({
		width	: dim.width,
		height	: dim.height,
		left	: dim.left,
		top		: dim.top
	}).fadeIn();

	//resizing the window resizes the $tf_bg_img
	$(window).bind('resize',function(){
		var dim	= getImageDim($tf_bg_img);
		$tf_bg_img.css({
			width	: dim.width,
			height	: dim.height,
			left	: dim.left,
			top		: dim.top
		});
	});

	//expand and fit the image to the screen
	$('#tf_zoom').live('click',
	function(){
		if($tf_bg_img.is(':animated'))
			return false;

		var $this	= $(this);
		if($this.hasClass('tf_zoom')){
			resize($tf_bg_img);
			$this.addClass('tf_fullscreen')
			.removeClass('tf_zoom');
		}
		else{
			var dim	= getImageDim($tf_bg_img);
			$tf_bg_img.animate({
				width	: dim.width,
				height	: dim.height,
				top		: dim.top,
				left	: dim.left
			},350);
			$this.addClass('tf_zoom')
			.removeClass('tf_fullscreen');	
		}
	}
	);
	
	//click the arrow down, scrolls down
	$tf_next.bind('click',function(){
		if($tf_bg_img.is(':animated'))
			return false;
		scroll('tb');
	});
	
	//click the arrow up, scrolls up
	$tf_prev.bind('click',function(){
		if($tf_bg_img.is(':animated'))
			return false;
		scroll('bt');
	});
	
	//mousewheel events - down / up button trigger the scroll down / up
	$(document).mousewheel(function(e, delta) {
		if($tf_bg_img.is(':animated'))
			return false;
			
		if(delta > 0)
			scroll('bt');
		else
			scroll('tb');
		return false;
	});
	
	//key events - down / up button trigger the scroll down / up
	$(document).keydown(function(e){
		if($tf_bg_img.is(':animated'))
			return false;
		
		switch(e.which){
			case 38:	
				scroll('bt');
				break;	

			case 40:	
				scroll('tb');
				break;
		}
	});
}

The next function takes care of showing the next or previous image:

function scroll(dir){
	//if dir is "tb" (top -> bottom) increment current, 
	//else if "bt" decrement it
	current	= (dir == 'tb')?current + 1:current - 1;
	
	//we want a circular slideshow, 
	//so we need to check the limits of current
	if(current == total) current = 0;
	else if(current < 0) current = total - 1;
	
	//flip the thumb
	$tf_thumbs.flip({
		direction	: dir,
		speed		: 400,
		onBefore	: function(){
			//the new thumb is set here
			var content	= '';
			content		+='<img src="' + $tf_bg_images.eq(current).attr('longdesc') + '" alt="Thumb' + (current+1) + '"/>';
			$tf_thumbs.html(content);
		}
	});

	//we get the next image
	var $tf_bg_img_next	= $tf_bg_images.eq(current),
	//its dimentions
	dim				= getImageDim($tf_bg_img_next),
	//the top should be one that makes the image out of the viewport
	//the image should be positioned up or down depending on the direction
	top	= (dir == 'tb')?$(window).height() + 'px':-parseFloat(dim.height,10) + 'px';
			
	//set the returned values and show the next image	
	$tf_bg_img_next.css({
		width	: dim.width,
		height	: dim.height,
		left	: dim.left,
		top		: top
	}).show();
		
	//now slide it to the viewport
	$tf_bg_img_next.stop().animate({
		top 	: dim.top
	},1000);
		
	//we want the old image to slide in the same direction, out of the viewport
	var slideTo	= (dir == 'tb')?-$tf_bg_img.height() + 'px':$(window).height() + 'px';
	$tf_bg_img.stop().animate({
		top 	: slideTo
	},1000,function(){
		//hide it
		$(this).hide();
		//the $tf_bg_img is now the shown image
		$tf_bg_img	= $tf_bg_img_next;
		//show the description for the new image
		$tf_content_wrapper.children()
		.eq(current)
		.show();
	});
	//hide the current description	
	$tf_content_wrapper.children(':visible')
	.hide()

}

The resize function will animate the image to a screen fitting size:

function resize($img){
	var w_w	= $(window).width(),
	w_h	= $(window).height(),
	i_w	= $img.width(),
	i_h	= $img.height(),
	r_i	= i_h / i_w,
	new_w,new_h;
	
	if(i_w > i_h){
		new_w	= w_w;
		new_h	= w_w * r_i;
		
		if(new_h > w_h){
			new_h	= w_h;
			new_w	= w_h / r_i;
		}
	}	
	else{
		new_h	= w_w * r_i;
		new_w	= w_w;
	}
	
	$img.animate({
		width	: new_w + 'px',
		height	: new_h + 'px',
		top		: '0px',
		left	: '0px'
	},350);
}

The last function will give us the dimensions of an image and its correct positioning:

function getImageDim($img){
	var w_w	= $(window).width(),
	w_h	= $(window).height(),
	r_w	= w_h / w_w,
	i_w	= $img.width(),
	i_h	= $img.height(),
	r_i	= i_h / i_w,
	new_w,new_h,
	new_left,new_top;
	
	if(r_w > r_i){
		new_h	= w_h;
		new_w	= w_h / r_i;
	}
	else{
		new_h	= w_w * r_i;
		new_w	= w_w;
	}


	return {
		width	: new_w + 'px',
		height	: new_h + 'px',
		left	: (w_w - new_w) / 2 + 'px',
		top		: (w_h - new_h) / 2 + 'px'
	};
}

And that was all the jQuery. Now, we want to embed some fonts. For that we will include the following references in the head of our HTML:

<link href='http://fonts.googleapis.com/css?family=PT+Sans+Narrow' rel='stylesheet' type='text/css' />
<link href='http://fonts.googleapis.com/css?family=Dancing+Script' rel='stylesheet' type='text/css' />

And that’s all! We hope you enjoyed the tutorial and learning something new today!

    Great tutorial,

    wanted to ask if there’s a way to make the images slide automatically ?

    thanks in advance

  2. 4

    another great tut and i have to say the you have a great taste, the picture you choose are amazing. and i think it will be very cool if we can make the text fade away once we click the magnifier on the thumbnail… can it be done ?

  3. 5

    wonderful wonderful !
    however, I’m working on a modification of this template.
    and can’t seem to get any variation of a lightbox effect to work, i’m trying to click on an image/icon i added to the tf_content area, to show a hidden div via modal/lightbox, but to no avail.
    any thoughts.

  4. 8

    Thank you ! Works great, though I had to do some adjustments to move the thumbnails a bit lower and replace the arrows. Other than that it is great.

  5. 10

    thank you mary for this tutorial :)
    i wanted to ask how can i make this slide autoplay ?

  6. 11

    Thank you for this tutorial.
    for those who ask about play automaticly here is the solution -> just add this code before the scroll() function
    ‘$(document).ready(function() {
    setInterval(function() { scroll(‘tb’)}, 2000);’
    });

  7. 14

    Hi, great tutorial.
    Would it be possible to flip the thumbnail and not a white area?
    Greetings

  8. 15

    Is there a way to make it so that the default of the large image is the zoomed out option and the user has the option to make it full size?
