jQuery Meta Image Overlay
This is an image overlay jQuery plugin that will allow you to display additional facts in a semi-transparent pane over an image that appears when a user hovers that image. And the special part of this plugin is that metadata plugin is already included.
This is just a simple jQUery plugin that presents an image with an overlaid title or caption in a graceful way. Google Code hosts this plugin and it doesn’t have any compatibility issues. It works from different browsers out there.
