All you have to do is login as administrator and click Add New -> Testimonial. This will appear in a toolbar across the top of your site.

You will be taken to a page where you can make an entry and upload an image. Don’t worry about the size of the image because it is resized with ImageMagick (Linux).

There are extra sections that can be expanded and entered like keywords, custom urls, page title, etc.. but they are optional and mostly auto-generated. We can use them when we need an extra edge to grab some more link juice.

That’s it.
