We’ve included a nice widget for you that displays the most recent posts with thumbnails. The thumbnails are automatically generated from the featured image you upload for the post(s). You can publish this in the left or right sidebars, or the bottom, or the footer.
…in the Footer Area:
Go to Appearance >> Widgets
Drag the Clarified Recent Posts widget into the sidebar position you want to show it in, and then use the settings to title it and how many posts to show.
