WP FancyBox is a plugin for WordPress to overlay images on the page with zoom animation using the modified version of FancyBox (http://fancy.klade.lv).

(Obviously, the above screenshots don't use FancyBox to appear -- we can't do this in Google Code, so they are just plain links to Flickr. Sample page is coming...)

Quick Guide

To display image in FancyBox, your img tag should include class size-thumbnail, e.g.:

<a href="large-image.png">
<img src="small-image.png" class="size-thumbnail">
</a>

WordPress does this automatically if you insert image with Thumbnail size via admin panel.
