This is a post that I want to write to avoid forgeting the process to include a watermark to a picture using Gimp software for Mac.

Why using a watermark in your pictures?

To protect your pictures of being used by someone that has not the rights of this picture you can add a watermark with the right level of opacity to avoid that someone else in the internet uses that picture.

Also you can use it to reinforce the brand name in your product/service because the potential clients will see your brand and will notice that your product is unique of your company, so a good candidate for your watermark is using the logo of your company for instance.
