Simple, easy to use, fancybox style popup.
Works for all images in your page that are in anchor tags. If it finds more than one, it will create a small gallery you can navigate through with the buttons or your keyboard. Advanced users can open iframes and html content in it fairly easily.
<h4>Avanced users</h4>
<h4>Basic use</h4>
Anchor class for popup: “hs-rsp-popup”
<h4>Advanced use</h4>
<ul>
<li>disable gallery feature and popup for image by adding this class: no-hsrsp-popup</li>
<li>anchor classes for iframe popup “hs-rsp-popup iframe”</li>
<li>anchor classes for html popup “hs-rsp-popup hiddendiv”</li>
</ul>
<h4>Examples</h4>
To popup an image give the anchor tag around the image this class: “hs-rsp-popup” 
Example: <code><a href="image.png" class="hs-rsp-popup"><img src="image.png" alt="image"/></a></code>
For an iframe, set the srct of the iframe and use the class “iframe” combined with “hs-rsp-popup”: 
 <a href="http://www.youtube.com/watch?hl=en-GB&v=2WNrx2jq184&gl=GB" title="Bird is the word" rel="nofollow ugc">Watch this</a>
You can also use this to show html content. For local content just use the id of the element for the href: 
 <a href="#elementid" rel="nofollow ugc">click here</a> 
 Hello, World!
For remote content, link to the page, for example: 
 <a href="http://www.hotscot.net" rel="nofollow ugc">click here</a>
<h4>Setting Popup Size (image/iframe)</h4>
You can use the following html5 data attributes in your link to set the size: <code>data-popupheight="100" data-popupwidth="300"</code> These values are in pixels.
For Example: 
 <a href="image.png" rel="nofollow ugc"></a>
Note: for this to work, you have to use both the data-popupwidth and data-popupheight attributes.
