Dynamically adds multiple featured image or multiple post thumbnail functionality to your page, posts and custom post types. This plugin provides you an interface to add any number of featured image as you want without writing a single line of code. These featured images can then be collected by the various theme functions.
Overview
Dynamic Featured Image enables the option to have MULTIPLE featured images within a post or page. 
This is especially helpful when you use other plugins, post thumbnails or sliders that use featured images. 
Why limit yourself to only one featured image if you can do some awesome stuffs with multiple featured image? 
DFI allows you to add different number of featured images to each post and page that can be collected by the various theme functions.
