The Replace Image plugin adds a button to the Attachment Details screen which allows you to upload or select an image to replace the current image while retaining the URL and attachment ID. This allows you to easily swap in an updated version of an image without having to re-select it in theme settings pages, post/page content, or anywhere else where it might be referenced.
Important: Disable your browser’s cache and any WordPress caching plugins before use; otherwise, the plugin may appear not to work. See Tools > Replace Image for instructions.

Replace Image

Old images and database entries remain, no links are updated to the new entries. I followed instructions -- no perceivable change. If it once worked, it no longer does.

Doesn't replace, just uploads new image

I was needing a plugin to enable the replacement of some broken media, tried others but they cannot do it, only replace existent media, and then Replace Image is the one that worked and fitted for my needs.

Great tool!

Upload a new version of an image without deleting the old image attachment, so that references to the image remain intact.
