I just figured out how to create a widget for a book that published my short story and it ended up being easy:
When you log into WordPress go to the front end of your site and you will see a drop down list after your site’s name on a banner at the very top of your page. Click it and choose the “widget” option. You will be taken to a list of available widgets, choose the “image” widget option. This will create a drop down menu. First you are asked to choose where you want to place the widget. Choose a location. Then you will be taken to a page that is needed to generate the content of the widget. For your image URL go to the Amazon page where your work is listed and right click on the image of the cover. This will produce a menu choose, “copy image location” and copy and paste the info into the image URL entry field on the “image” widget. You can add a caption explaining the importance of the widget. Then you can copy and paste the URL of the webpage where the book is located in Amazon into the “Link URL” entry field, and it will direct anyone who clicks it to your work’s sales page where they can buy it if they want.
Once that is set up you now have a widget of any published works. It’s simple enough when you know how it’s done, but it may take a while for a newbie to figure it out. The support page I looked this up on left some stuff unsaid so I decided to add an extra WordPress Webdesign tip to this site as a courtesy to any reader who could use the information.
