Create an image Popup
This tutorial requires the Image Manager and Link plugins. The entire process is simplified when using the Image Manager Extended, a subscription plugin
An image popup is typically launched from a thumbnail, or smaller version of the target image, but can also be launched from a text link. If you are using a text link, skip to step 2.
* A browser cookie is used to store the autopopup state - whether it has been opened already - when using Autopopup Single.
Example HTML created by these steps :
<a href="/images/Desert.jpg" class="jcepopup" rel="title[Desert];caption[Picture of a desert];group[nature]"><img src="/images/thumbnails/Desert_thumb.jpg" width="150" height="90" alt="Desert" /></a>
Simple gallery using a table and 2 grouped images
