Customizing the Shared Image with Add Link to Facebook
The second step of the guide to the Add Link to Facebook WordPress plugin is to look at the additional features of the plugin, which start with adding a profile picture.
Step 1) On the ‘Add Link to Facebook’ page, scroll down to ‘Additional Settings’ and choose ‘Picture’ from the Toolbar.
Step 2) You have a choice of adding a variety of images to your posts when they are published on your page, from a WordPress logo, first attached image on the post, the featured image, a pic of the author or a custom picture, which you can add via image URL.
Step 3) If you want to set a default picture URL, add the URL in the box provided and choose the size from the list below (thumbnail, medium or large).
Step 4) If you have a URL news feed icon, add it in the box provided, and then click ‘Save’.
