Watermark Plugin Installation

To previous bidders: There has been a change in requirements

I will need a watermark plugin to be installed on my website.

- When I upload images on the website, the watermark will appear on the image instantly
- There are photos that were uploaded previously, when you install the plugin, you need to ensure that the watermark appear on the photos that were previously uploaded
-No customization of watermark needed

There are many plugins on the Internet. You can find a plugin that have features similiar to this and I will need you to customize it so that it is working properly on my website's dashboard (Not administrator dashboard)

When you bid, I will need you to send a message on what plugin you intend to use and the turn around time.
