With this pluginyou can face two goals:
· File Replace Sometimes you have an image used in several spots (slider, gallery, feature image, …) and if you remove it and upload it again, as it gets a new ID, you will need to select the new one all around but you could forget a place. To avoid it, use this plugin.
· File Rename Sometimes we upload a file as it comes from the mobile camera and later we realize that the file doesn´t have a ver SEO-Friendly name. Here you can rename the file.
None of both functionalities will breake any link where the image is pointed by its ID but this action doesn´t do a Search and Replace along the post entries.

FileRenameReplace

This plugin let the user renaming or replacing files without breaking links.

Unique uploaded media names by adding some extra random string.
By default, WordPress upload file name slugs at it are. Sometimes if any file name conflicts, WordPress adds extra suffix at the end of the slug name.
Example: <code>my-image.jpg</code> and if the file name is similar, <code>my-image-1.jpg</code> <code>my-image-2.jpg</code> and so on.

Unique Uploaded Media Name

Although, most of the time I personally prefer to uploaded contents should have a unique string in order to identify them easily. I thought it would be great if I submit a plugin which may help others.

A very lightweight plugin which requires 3.02 Kilobytes of space.
