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.
By installing this plugin, every uploaded media will have unique values as a suffix at the end of the uploaded media name. Default uploaded string value is 15 character and have zero possibility of file name confliction. <code>Uploaded file name + Unique String</code>
Example
<ul>
<li>my-image-475445-SIu7oQGW.jpg</li>
<li>my-image-311629-TFuNSyHH.jpg</li>
</ul>

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.
