Shadowbox
Open thumbnails, images (and much more) with Shadowbox.js.
With Shadowbox.js attachments and image will open within a nice modal window. But thats not all: It can open external web resources and flash animations too. Also this plugin provides a spolier support, so you can load whatever you want with Shadowbox.js. Attachments can be load in a gallery mode and big images will be resized to screen.Compatibility
