In WordPress, attachments default to having their own pages. Sometimes, this is not desirable, as in search engine results. Use this small plugin to redirect your attachment pages to the post parent using a 301 redirect (post parents are also searched for by post name). If an attachment parent post cannot be found, it redirects to your blog home page with a 302 redirect.
Installation: A no-brainer.
Requirements: Wordpress 3.0 or higher.

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.
