This plugin is a must-have for anyone who is serious about SEO.
On a single author blog, you might already know that you should rename your files offline before uploading to your WP site.
But if you handle a multi-author blog, you'll find your authors don't follow your SEO guidelines. Soon, your media library is full of filenames like DSC_0032.jpg which tells the search engines nothing.
Media File Renamer takes care of that for you. I use it before publishing any post by an author.
Thanks for the great plugin!
