⚠️ Attention! This repository will be maintained just in small iteration. The plugin is easy to use, but its customization can be troublesome. To improve plugin’s flexibility, I made another repository PhotoViewer which is the enhanced version of Magnify.

[ website ]


  • Modal draggable
  • Modal resizable
  • Modal maximizable
  • Image movable
  • Image zoomable

  • Fullscreen showing
  • Multiple instances

You can install the plugin via npm

or via bower

$ bower install jquery.magnify --save


1.Include files

The usage of magnify is very simple.

<link href="/path/to/magnify.css" rel="stylesheet" />

<script src="/path/to/jquery.js"></script>
<script src="/path/to/jquery.magnify.js"></script>

The icons in magnify use svg default, you can customize them in options.

2.Html structure

The default structure as below:

<a data-magnify="gallery" href="big-1.jpg">
  <img src="small-1.jpg" />
<a data-magnify="gallery" href="big-2.jpg">
  <img src="small-2jpg" />
<a data-magnify="gallery" href="big-3.jpg">
  <img src="small-3.jpg" />


<img data-magnify="gallery" data-src="big-1.jpg" src="small-1.jpg" />
<img data-magnify="gallery" data-src="big-2.jpg" src="small-2.jpg" />
<img data-magnify="gallery" data-src="big-3.jpg" src="small-3.jpg" />

All structures above have optional attributes as below:

  • Add a data-src attribute to link big image if you do not want to use a <a> tag. If you use it in a <a> tag, it will override the image link in href attribute.
  • Add a data-caption attribute if you want to show a caption. If you are not using this attribute, it will show the image name in the url when you set the title option true.

You can define callbacks in callbacks option. In each callback you can get the Magnify instance with this or context.

  callbacks: {

      // Will fire before modal is opened
    opened: function (context) {

    changed: function (context, index) {
      // Will fire after image is changed
      // The argument index is the next image index of image group
