WordPress 3.0+ is great. It shows you your uploaded header images. 
It’s too bad it doesn’t let you delete them as well! 
The answer is here with a simple yet extremely useful little plugin called Delete Custom Header. 
Unlike WP’s “Remove Header” button, this plugin completely removes the header image data 
from the database and the files from the server.
For themes with a header option, like Twenty Ten, Twenty Eleven, etc.

More info:
This plugin is designed to work out of the box with a large number of popular themes if not all 
the menu container and then manipulating the HTML tag w/ said class by way of JS
Plugins tested to work with this theme work a tad bit differently. Instead of 
adding a class it uses custom js files that have the main navigational selectors 
already defined. JS manipulates the menus by using the already defined tags.
