First, create the image you want to use. In this case the image was cropped to 350 x 350 px. Then upload it to your media library. After you have uploaded the image click on the image and copy the URL of its location. Then go to your widgets in Appearance/Widgets.
The Author widget used was created using a ‘text’ widget. In the Appearance/Widget area pull the [Text] widget into the Primary sidebar area. Then type the title you want (you don’t have to enter a title if you don’t want one). Then in the text area below the title enter code like this (exchange https://www.mywebsite.com with your website name and use the url of your image in the url section for the image after src= ).
Then enter the URL for the page you want the ‘More about me’ link to point to after the a href= section.
You should also check the box [Automatically add paragraphs] at the bottom of the widget so that your paragraph will start on a new line and not butt right up against your image.
Then click Save. Now wherever the primary sidebar is displayed on your website this widget will appear.
