Kentico allows you to specify a watermark that will overlay the images used throughout the system.

You can have the system automatically apply watermarks to the following images:

- Page attachment images
- Media library images
- Object attachment (metafile) images

## To add watermarks to images

1. Navigate to **Settings -> System -> Files**.
2. Specify the watermark image that you want to use:
   1. By a full relative path, for example, _\~/CorporateSite/media/images/watermark.jpg_– OR –
   2. By specifying the watermark image file name placed in _\~/CMS/App\_Themes/Default/Images/Watermarks_. For example, _watermark.jpg._
3. Configure the other watermark [properties](https://docs.kentico.com/k11/configuring-kentico/managing-sites/configuring-settings-for-sites/settings-system/settings-files.md).
4. **Save**.

The watermark will now be applied to all the images for which it was configured.
