Hi,
Easier way is to use our HOT Photo Gallery plugin :
demo.hotjoomlatemplates.com/test/index.p...icle&id=52&Itemid=64
or you can try something manually like this:
You must use HTML view in article editor to add some markup and javascript.
This would be what you need to add:
<div id="mysingleimagegallery">
<a href="<Full size image path>"><img src="<thumb path>" alt="lightbox" /></a>
</div>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('#mysingleimagegallery a').lightBox();
});
</script>
<Full size image path> and <thumb path> should be replaced with real paths.
