General Settings


Image Watermark plugin lets you enable image watermarking automatically or manually. It also lets you choose which size you want to enable the watermark, we strongly recommend to avoid enabling this option for the full image size so you can be able to remove or change the watermark in case you change your mind.

Watermark Position Settings


Watermark Plugin lets you choose your watermark alignment position and the x:y offset(in pixels).

Watermark Main Settings


To add and style your Watermark you should go and edit the plugin's Main Settings. You can choose your desired watermakr image, scale it and format it as you wish while you can preview it before applying the chosen setting.

Image Protection and Backup Settings


You can also disable the right click feature(again we suggest to avoid enable this setting), prevent the drag and drop feature and set the back settings for your images.

How to remove watermark from your images


Considering the fact that you didn't enable the Watermark for the Full Image Size you can use the reGenerate Thumbnails Advanced plugin and restore your images back to the default ones.

Protect your images prior uploading them to your WordPress Site

Usually the first step is to protect the image itself prior uploading it and using it on your site.
This can be done using various methods like IPTC MetaData where your copyright info can also be stored in the image file's metadata. IrfanView is a simple and lightweight photo editor which can help you add the IPTC Metadata.
Another way to add your copyright info to an image is through Image Noise using Digimarc(built into Photoshop by default) which digitally encodes the watermark as image noise that is imperceptible to our eyes, but detectable by a computers with the appropriate software installed. Be careful though because this method increases the total size of your image.
