If you find yourself working with a lot of images or other media files in WordPress, chances are good that at some point you’ll need to change a file’s content while still keeping links and image placement the same. The best way we’ve found to do this is with a free plugin called “Enable Media Replace”. In this Quick Guide, we’ll teach you how to install this plugin and use it to replace images that already exists or media files on your WordPress site.

It’s a bit odd that WordPress doesn’t let you rename your media files. For a feature with some usability questions and a lot of SEO questions (Google, of course, reads the filenames of images as a clue to what they’re about), it’s surprising that WordPress’s best out-of-the-box solution is to simply delete and reupload whatever files you’d like to have renamed.
