fancyBox is a tool that offers a nice and elegant way to add zooming functionality for images, html content and multi-media on your webpages. It is built on the top of the popular JavaScript framework jQuery and is both easy to implement and a snap to customize.

What's new

Version 2 is completely rewritten with new features and updated graphics.

Notable changes


Download the plugin, unzip it, copy files and include fancyBox script and stylesheet in your document (you will need to make sure the css and js files are on your server, and adjust the paths in the script and link tag). Make sure you also load the jQuery library. Example:

<!-- Add jQuery library -->
<script type="text/javascript" src=""></script>

<!-- Add mousewheel plugin (this is optional) -->
<script type="text/javascript" src="/fancybox/lib/jquery.mousewheel-3.0.6.pack.js"></script>

<!-- Add fancyBox -->
<link rel="stylesheet" href="/fancybox/source/jquery.fancybox.css?v=2.1.5" type="text/css" media="screen" />
<script type="text/javascript" src="/fancybox/source/jquery.fancybox.pack.js?v=2.1.5"></script>

<!-- Optionally add helpers - button, thumbnail and/or media -->
<link rel="stylesheet" href="/fancybox/source/helpers/jquery.fancybox-buttons.css?v=1.0.5" type="text/css" media="screen" />
<script type="text/javascript" src="/fancybox/source/helpers/jquery.fancybox-buttons.js?v=1.0.5"></script>
<script type="text/javascript" src="/fancybox/source/helpers/jquery.fancybox-media.js?v=1.0.6"></script>

<link rel="stylesheet" href="/fancybox/source/helpers/jquery.fancybox-thumbs.css?v=1.0.7" type="text/css" media="screen" />
<script type="text/javascript" src="/fancybox/source/helpers/jquery.fancybox-thumbs.js?v=1.0.7"></script>

Create link elements whose href attributes will contain the path of the element you wish to open within the fancyBox.

<a class="fancybox" rel="group" href="big_image_1.jpg"><img src="small_image_1.jpg" alt="" /></a>
<a class="fancybox" rel="group" href="big_image_2.jpg"><img src="small_image_2.jpg" alt="" /></a>

Attach fancyBox when the document is loaded. If you are not familiar with jQuery, please, read this tutorial for beginners.

<script type="text/javascript">
	$(document).ready(function() {

Tips & tricks

A collection of the demos created in response to questions

  1. Change overlay color and opacity
  2. Title -
  3. Disable right click (add watermark)
  4. Remove white border around content
  5. Move navigation arrows outside -
  6. Customize/change the content -
  7. Fade content when changing gallery items
  8. Apply fancyBox on all images
  9. Start the gallery with only one preview picture:
  10. Launch fancyBox on page load:
  11. Reload page after closing
  12. Set parameters (like width and height) individually -
  13. Supersized effect
  14. Using YouTube API - go to the next video after the current one is finished playing
  15. Open PDF (inside iframe)
  16. Disable "locked" feature - the content is locked in the overlay by default
  17. Simple "dotted" navigation


You can also go straight into action and open a standalone version of demo and view its source code.

Note: ID's are single use and are only applied to one element.
Galleries are created from elements who have the same "data-fancybox-group" or "rel" attribute value.

Script uses the `href` or `data-fancybox-href` attribute of the matched elements to obtain the location of the content and to figure out content type you want to display. You can specify type directly by adding classname (fancybox.image, fancybox.iframe, etc) or `data-fancybox-type` attribute. Use `title` or `data-fancybox-title` attribute to specify item caption.

Alternatively, you can set content type as an option: $(".open_ajax").fancybox({type: 'ajax'});.

Note, ajax requests are subject to the same origin policy. If fancyBox will not be able to get content type, it will try to guess based on 'href' and will quit silently if would not succeed (this is different from previous versions where 'ajax' was used as default type or an error message was displayed).

Extended functionality

Remember to include the necessary files! Each helper is located in separate files.

The plugin comes with a number of public functions to help you utilize the plugin in a number of different scenarios. Each of these functions can be called as a property of the $.fancybox object.
To use from inside the iframe - <a href="javascript:parent.$.fancybox.close();">Close me</a>

Name Description

$ [group], [options] )

Launch fancyBox, the same as $.fancybox([group], [options])
First parameter can be in various types, examples:
$.fancybox([ {href : 'img1.jpg', title : 'Title'}, {href : 'img2.jpg', title : 'Title'} ]); - array containing objects
$.fancybox( {href : 'image.jpg', title : 'Lorem lipsum'} ); - single object
$.fancybox( ['image.jpg', 'image.jpg'] ); - array containing links as strings
$.fancybox( 'image.jpg' ); - string as source link
$.fancybox( [jQuery object] );
$.fancybox( '<h1>Lorem lipsum</h1>' );


Cancel loading image or abort ajax request

$.fancybox.close( [force] )

If fancyBox is fully opened (open animation has ended) then start closing animation. If not or closing is forced (e.g. called like $.fancybox.close( true )) than fancyBox is removed immediatly


Start or stop (if already running) slideshow


Navigate to next gallery item


Navigate to previous gallery item

$.fancybox.jumpto( [index] )

Navigate to gallery item by index. Item counting starts from 0, e.g. $.fancybox.jumpto( 0 ); will open the first, e.g. $.fancybox.jumpto( 1 ); will second, etc


Will center fancyBox inside viewport and toggle position type to fixed or absolute if needed


Auto-sizes fancyBox height to match height of content


If content is resized to fit inside viewport than it will be expanded to full size (and vice verse)


Shows loading animation


Hides loading animation

Also available are event driven callback methods, allowing you to extend functionality:

Name Description
onCancel Called after user triggers canceling.
Note: If false is returned by the callback, the canceling will be halted
beforeLoad Called before starting to load content.
Note: If false is returned by the callback, the loading will be halted
afterLoad Called after content is loaded. Receives two arguments - upcoming and current object -
Note: If false is returned by the callback, the content will not be shown.
beforeShow Called right before open animations has started
afterShow Called after open animations has ended
beforeClose Called right after closing has been triggered but not yet started
Note: If false is returned by the callback, the closing will be halted.
afterClose Called after closing animation has ended
onUpdate Called after window resize, scroll or orientation change events are triggered
onPlayStart Called after slideshdow has started
onPlayEnd Called after slideshdow has stoped


Helpers provide a simple mechanism to extend the capabilities of fancyBox. There are two built-in helpers - 'overlay' and 'title'. You can disable them, set custom options or enable other helpers. Examples:

//Disable title helper
    helpers:  {
        title:  null

//Disable overlay helper
    helpers:  {
        overlay : null

//Change title position; show overlay after content has loaded
    helpers:  {
        title : {
            type : 'inside'
        overlay : {
            showEarly : false

//Enable thumbnail helper and set custom options
    helpers:  {
        thumbs : {
            width: 50,
            height: 50

Options for thumbnail helper

Name Description
width Thumbnail width
height Thumbnail height
source Function to obtain the URL of the thumbnail image. By default, it uses the first image inside anchor or loads destination url instead.

position 'top' or 'bottom'

Options for button helper

Name Description
tpl HTML template
position 'top' or 'bottom'


You can ask a questions using the StackOverflow site where you are most likely to get answer quickly as many Javascript experts spend time on the site. Make sure you add the tags "jquery" and "fancybox" when posting.

If you run into an issue and need to report a bug, please create an issue on GitHub issues and I will investigate. But do not forget to check FAQ, first!

Follow @thefancyapps for the latest updates.

1. It doesn't work at all. The image opens up in a new page. What's wrong?

Check if you have included all files and set up FancyBox correctly.

Look for JavaScript error messages, they might help you to locate the problem.

If you see something like Uncaught TypeError: undefined is not a function:
1) Check if fancybox.js file is indeed loaded
2) Check if you have not included jQuery library more than once

2. Can a FancyBox appear over the top of my Flash content?

Yes, read this explanation

3. Can the script be called from an iframe?

If all necessary files are included in the parent window, then you can, like:
<a href="javascript:parent.${href : 'myurl'});">Open something</a>

4. How can I close FancyBox from other element? ?

Just call $.fancybox.close() on your onClick event

5. I`m using custom urls for images (for example, PHP created images - index.php?action=image&id=123) and FancyBox shows source of image. Why?

FancyBox gueses content type from url but sometimes it can be wrong. The solution is to force your type, like so - $(".selector").fancybox({'type' : 'image'});

6. FancyBox is not working on all images, only first one opens. What's wrong?

If you are using ID as selector $("#selector").fancybox(); then switch to classes - $(".selector").fancybox();
